Redetermination of the perovskite-type compound YRh(3)B revealing a Rh deficiency.

ABSTRACT: In contrast with previous structural studies of ytterbium trirhodium boride, YbRh(3)B, that suggest a boron deficiency, the current redetermination of the crystal structure of YbRh(3)B revealed instead a rhodium deficiency with a refined composition of YbRh(2.67?(2))B. In the ABX(3) perovskite-type structure, Yb, B and Rh are located on the A, B and X positions, respectively, with site symmetries of mm for the A and B sites, and 4/mm.m for the X site.

Redetermination of terbium scandate, revealing a defect-type perovskite derivative.

Project description:The crystal structure of terbium(III) scandate(III), with ideal formula TbScO(3), has been reported previously on the basis of powder diffraction data [Liferovich & Mitchell (2004 ▶). J. Solid State Chem.177, 2188-2197]. The current data were obtained from single crystals grown by the Czochralski method and show an improvement in the precision of the geometric parameters. Moreover, inductively coupled plasma optical emission spectrometry studies resulted in a nonstoichiometric composition of the title compound. Site-occupancy refinements based on diffraction data support the idea of a Tb deficiency on the A site (inducing O defects on the O2 position). The crystallochemical formula of the investigated sample thus may be written as (A)(□(0.04)Tb(0.96))(B)ScO(2.94). In the title compound, Tb occupies the eightfold-coordinated sites (site symmetry m) and Sc the centres of corner-sharing [ScO(6)] octa-hedra (site symmetry ). The mean bond lengths and site distortions fit well into the data of the remaining lanthanoid scandates in the series from DyScO(3) to NdScO(3). A linear structural evolution with the size of the lanthanoid from DyScO(3) to NdScO(3) can be predicted.

Redetermination of AgNb(2)PS(10) revealing a silver deficiency.

Project description:In comparison with a previous crystallographic study [Goh et al. (2002 ?). J. Solid State Chem.168, 119-125] of the title compound, silver diniobium tris-(disulfide) tetra-thio-phosphate(V), that reports a full occupation of the silver position and isotropic displacement parameters for the atoms, the current redetermination reveals a silver deficiency with a site-occupation factor of 0.88?(1) and reports all atoms with anisotropic displacement parameters. The structure of Ag(0.88)Nb(2)PS(10) is composed of (?) (1)[Nb(2)PS(10)] chains, which are built up from pairs of distorted bicapped trigonal-prismatic [NbS(8)] polyhedra forming [Nb(2)S(12)] dimers and of tetra-hedral [PS(4)] groups. These chains are connected via the statistically disordered Ag(+) ions, forming double layers. Adjacent layers are stacked solely through van der Waals forces into a three-dimensional structure. Short and long Nb-Nb distances [2.880?(1) and 3.770?(2)?Å, respectively] alternate along the chain and S(2) (2-) and S(2-) anionic species are observed.

Redetermination of Nd2Ti2O7: a non-centrosymmetric structure with perovskite-type slabs.

Project description:Single crystals of dineodymium(III) dititanium(IV) hepta-oxide, Nd2Ti2O7, were synthesized by the flux method and found to belong to the family of compounds with perovskite-type structural motifs. The asymmetric unit contains four Nd, four Ti and 14 O-atom sites. The perovskite-type slabs are stacked parallel to (010) with a thickness corresponding to four corner-sharing TiO6 octa-hedra. The Nd and Ti ions are displaced from the geometrical centres of respective coordin-ation polyhedra so that the net polarization occurs along the c axis. The investigated crystals were all twinned and have a halved monoclinic unit cell in comparison with the first structure determination of this compound [Scheunemann & Müller-Buschbaum (1975 ▶). J. Inorg. Nucl. Chem. 37, 2261-2263].

Redetermination of the crystal structure of RhPb<sub>2</sub> from single-crystal X-ray diffraction data, revealing a rhodium deficiency.

Project description:RhPb2 (rhodium dilead) is a superconductor crystallizing in the CuAl2 structure type (space group I4/mcm). The Rh and Pb atoms are located at the 4a (site symmetry 422) and 8h (m.2m) sites, respectively. The crystal structure is composed of [RhPb8] anti-prisms, which share their square faces along the c axis and the edges in the direction perpendicular to the c axis. We have succeeded in growing single crystals of RhPb2 and have re-determined the crystal structure on basis of single-crystal X-ray diffraction data. In comparison with the previous structure studies using powder X-ray diffraction data [Wallbaum (1943 ▸). Z. Metallkd. 35, 218-221; Havinga et al. (1972 ▸). J. Less-Common Met. 27, 169-186], the current structure analysis of RhPb2 leads to more precise unit-cell parameters and fractional coordinates, together with anisotropic displacement parameters for the two atoms. In addition and likewise different from the previous studies, we have found a slight deficiency of Rh in RhPb2, leading to a refined formula of Rh0.950 (9)Pb2.

Redetermination of the distorted perovskite Nd(0.53)Sr(0.47)MnO(3).

Project description:Neodymium strontium manganese oxide with ideal composition Nd(0.5)Sr(0.5)MnO(3) was reported to have two different structure models. In one model, the x coordinate of an O atom is at x > 1/2, while in the other model the x-coordinate of this atom is at x < 1/2. Difference-density maps around this O atom obtained from the current redetermination clearly show that the structure with the O atom at x < 1/2 result in a more satisfactory model than that with x > 1/2. The title compound with a refined composition of Nd(0.53 (5))Sr(0.47 (5))MnO(3) is a distorted perovskite-type structure with site symmetries 2mm for the statistically occupied (Nd, Sr) site and for the above-mentioned O atom, .2/m. for the Mn atom and ..2 for a second O-atom site. In contrast to previous studies, the displacement factors for all atoms were refined anisotropically.

Revealing the detailed path of sequential deposition for metal halide perovskite formation.

Project description:Sequential deposition has been extensively used for the fabrication of perovskite solar cells. Nevertheless, fundamental aspects of the kinetics of methylammonium lead iodide perovskite formation remain obscure. We scrutinize the individual stages of the reaction and investigate the crystallization of the lead iodide film, which occurs before the intercalation of methylammonium iodide commences. Our study identifies the presence of mixed crystalline aggregates composed of perovskite and lead iodide during intercalation and structural reorganization. Furthermore, Ostwald ripening occurs in the film for reaction times beyond the point of conversion to perovskite. Using cross-sectional confocal laser scanning microscopy for the first time, we reveal that lead iodide in the over-layer and at the bottom of the mesoporous layer converts first. We identify unreacted lead iodide trapped in the mesoporous layer for samples of complete conversion. We acquire kinetic data by varying different parameters and find that the Avrami models best represent them. The model facilitates the rapid estimation of the reaction time for complete conversion for a variety of reaction conditions, thereby ascertaining a major factor previously determined by extensive experimentation. This comprehensive picture of the sequential deposition is essential for control over the perovskite film quality, which determines solar cell efficiency. Our results provide key insights to realize high-quality perovskite films for optoelectronic applications.

Revealing the role of organic cations in hybrid halide perovskite CH3NH3PbI3.

Project description:The hybrid halide perovskite CH3NH3PbI3 has enabled solar cells to reach an efficiency of about 20%, demonstrating a pace for improvements with no precedents in the solar energy arena. Despite such explosive progress, the microscopic origin behind the success of such material is still debated, with the role played by the organic cations in the light-harvesting process remaining unclear. Here van der Waals-corrected density functional theory calculations reveal that the orientation of the organic molecules plays a fundamental role in determining the material electronic properties. For instance, if CH3NH3 orients along a (011)-like direction, the PbI6 octahedral cage will distort and the bandgap will become indirect. Our results suggest that molecular rotations, with the consequent dynamical change of the band structure, might be at the origin of the slow carrier recombination and the superior conversion efficiency of CH3NH3PbI3.

Crystal structure of the Anderson-type hetero-polyoxometalate; K2[H7Cr(III)Mo6O24]·8H2O: a redetermination revealing the position of the extra H atom in the polyanion.

Project description:The title compound contains a symmetric hydrogen bond in which the H atom does not lie on a crystallographic centre of symmetry. The structure of K2[H7Cr(III)Mo6O24]·8H2O, namely dipotassium hepta-hydrogen hexa-molybdochromate(III) octa-hydrate, previously reported by Lee [Acta Cryst. (2007), E63, i5-i7], has been redetermined in order to locate the position of the seventh H atom in the anion. Six of the H atoms are bonded to the six ?3-O atoms and form hydrogen bonds of medium strength either to water mol-ecules or to the terminal O atoms of other polyanions. The seventh H atom forms a very short hydrogen bond between two ?2-O atoms on adjacent polyanions. This short bond, together with two normal hydrogen bonds, link the two crystallographically distinct centrosymmetric polyanions into chains along [011], while the length of this bond [2.461?(3)?Å] suggests that the H atom lies at its centre, but unusually for such a bond, this point is not a crystallographic centre of symmetry.

Single-Particle Catalysis: Revealing Intraparticle Pacemakers in Catalytic H<sub>2</sub> Oxidation on Rh.

Project description:Self-sustained oscillations in H2 oxidation on a Rh nanotip mimicking a single catalytic nanoparticle were studied by in situ field emission microscopy (FEM). The observed spatio-temporal oscillations result from the coupling of subsurface oxide formation/depletion with reaction front propagation. An original sophisticated method for tracking kinetic transition points allowed the identification of local pacemakers, initiating kinetic transitions and the nucleation of reaction fronts, with much higher temporal resolution than conventional processing of FEM video files provides. The pacemakers turned out to be specific surface atomic configurations at the border between strongly corrugated Rh{973} regions and adjacent relatively flat terraces. These structural ensembles are crucial for reactivity: while the corrugated region allows sufficient oxygen incorporation under the Rh surface, the flat terrace provides sufficient hydrogen supply required for the kinetic transition, highlighting the importance of interfacet communication. The experimental observations are complemented by mean-field microkinetic modeling. The insights into the initiation and propagation of kinetic transitions on a single catalytic nanoparticle demonstrate how in situ monitoring of an ongoing reaction on individual nanofacets can single out active configurations, especially when combined with atomically resolving the nanoparticle surface by field ion microscopy (FIM).

High performance organic-inorganic perovskite-optocoupler based on low-voltage and fast response perovskite compound photodetector.

Project description:Organic-inorganic hybrid photodetectors attract considerable attention because they can combine the advantages of both organic and inorganic systems. Here, a perovskite compound with a broad absorption spectrum and high power conversion efficiency is used as a photosensitive layer in an organic/inorganic hybrid heterojunction photodetector with a high and fast response. The high sensitivity exceeding 10(4) is obtained at bias of 0-4 V. Using a tandem organic light-emitting diode (OLED) as the light source, we fabricated an optocoupler device. The optocoupler achieved a maximum photoresponsivity of 1.0 A W(-1) at 341.3 ?Wcm(-2) at an input voltage of 6 V. The device also exhibits rapid response times of ?(rise) ~ 20 ?s and ?(fall) ~ 17 ?s; as well as a high current transfer ratio (CTR) of 28.2%. After applying an amplification circuit, the CTR of the optocoupler increases to 263.3%, which is comparable with that of commercial inorganic optocouplers. The developed hybrid optocoupler thus shows great promise for use in photonics.
