KInAs₂O₇, a new diarsenate with the TlInAs₂O₇ structure type.

ABSTRACT: Potassium indium diarsenate(V) was grown under mild hydro-thermal conditions (T = 493?K, 7?d) at a pH value of about 1. It adopts the TlInAs₂O₇ structure type (P-1, Z = 4) and is closely related to the KAlP₂O₇ (P2₁/c) and RbAlAs₂O₇ (P-1) structure types. The framework topology of KInAs₂O₇ is built of two symmetrically non-equivalent As₂O₇ groups which share corners with InO₆ octa-hedra. The K atoms are located in channels extending along [010].

Crystal structure of CsCrAs2O7, a new member of the diarsenate family.

Project description:Caesium chromium(III) diarsenate(V), CsCrAs2O7, was prepared by solid-state reactions. The title structure consists of isolated CrO6 octa-hedra and As2O7 diarsenate groups, sharing corners to build up a three-dimensional [CrAs2O7](-) anionic framework. In this framework, channels extending parallel to [001] are present in which the ten-coordinate Cs(+) ions reside. CsCrAs2O7 is isotypic with the monoclinic A (I) M (III) X 2O7 (A (I) = alkali metal; M (III) = Al, Cr, Fe; X = As, P) type I family of compounds crystallizing in the space group P21/c.

New mixed aluminium-chromium diarsenate.

Project description:Potassium chromium aluminium diarsenate, KCr1/4Al3/4As2O7, was prepared by solid-state reaction. The structure consists of (Cr1/4/Al3/4)O6 octa-hedra and As2O7 diarsenate groups sharing corners to build up a three-dimensional anionic framework. The potassium cations are located in wide channels running along the c-axis direction. The crystal structure is isostructural with the triclinic AIMIIIX2O7 (AI = alkali metal; MIII = Al, Cr, Fe; X = As, P) compounds. However, the MIII octa-hedrally coordinated site is 25% partially occupied by chromium and 75% by aluminium.

Barium zinc diarsenate.

Project description:The title compound, BaZnAs(2)O(7), belongs to the family of isotypic series of compounds adopting the general formula M1(2+)M2(2+)X(2)O(7) (M1(2+) = Ca, Sr, Ba or Pb; M2(2+) = Mg, Cr, Mn, Fe, Co, Ni, Cu, Zn or Cd; X = P or As). Suitable single crystals were prepared under hydro-thermal conditions. The framework structure is characterized by corner-sharing ZnO(5) square pyramids and As(2)O(7) groups where the Zn atoms occupy channels. X-ray diffraction analysis of single crystals twinned by non-merohedry [twin plane is (100)] yielded formula BaZnAs(2)O(7). Raman spectra confirmed the presence of a non-linear As-O-As linkage.

A New Cation-Ordered Structure Type with Multiple Thermal Redistributions in Co2 InSbO6.

Project description:Cation ordering in solids is important for controlling physical properties and leads to ilmenite (FeTiO3 ) and LiNbO3 type derivatives of the corundum structure, with ferroelectricity resulting from breaking of inversion symmetry in the latter. However, a hypothetical third ABO3 derivative with R32 symmetry has never been observed. Here we show that Co2 InSbO6 recovered from high pressure has a new, ordered-R32 A2 BCO6 variant of the corundum structure. Co2 InSbO6 is also remarkable for showing two cation redistributions, to (Co0.5 In0.5 )2 CoSbO6 and then Co2 InSbO6 variants of the ordered-LiNbO3 A2 BCO6 structure on heating. The cation distributions change magnetic properties as the final ordered-LiNbO3 product has a sharp ferrimagnetic transition unlike the initial ordered-R32 phase. Future syntheses of metastable corundum derivatives at pressure are likely to reveal other cation-redistribution pathways, and may enable ABO3 materials with the R32 structure to be discovered.

Ge0.57Ti0.43O2: a new high-pressure material with rutile-type crystal structure.

Project description:Single crystals of a GeO2-TiO2 solid solution with the corresponding composition Ge0.57Ti0.43O2 (germanium titanium tetra-oxide) were obtained by devitrification of germania-titania glass at high pressure and temperature. The new compound crystallizes in the rutile structure type (space group P42/mnm), where Ge and Ti share the same position M (site symmetry m.mm), with occupancy values of 0.57?(3) and 0.43?(3), respectively, and one O-atom position (m.2m). The M site is in a sixfold O-atom coordination and, as in the original TiO2 rutile structure, an elongation of the O-M-O bonds along the c-axis direction of the coordination polyhedron and deviation of the angles from 90° lead to a decrease in the coordination symmetry from octa-hedral to tetra-gonal. The Ge and Ti atoms are fully disordered in the structure, which indicates that the rutile structure is surprisingly pliant given the differing sizes of the two cations.

Disodium tris-(dioxidomolybdenum) bis-(diarsenate).

Project description:The asymmetric unit of the title compound, Na(2)(MoO(2))(3)(As(2)O(7))(2), is composed of two cyclic MoAs(2)O(11) units and an MoO(6) corner-sharing octa-hedron. The anionic framework can be decomposed into two types of layers, viz. MoO(2)As(2)O(7) and Mo(2)As(2)O(14), which use mixed Mo-O-As and As-O-Mo bridges to achieve a new three-dimensional structure with two types of large channels in which the Na(+) cations are located. Two O atoms are disordered and are located in two positions close to their initial positions with occupancy ratios of 0.612?(17):0.388?(17) and 0.703?(12):0.298?(12).

Synthesis, crystal structure and charge-distribution validation of a new alluaudite-type phosphate, Na2.22Mn0.87In1.68(PO4)3.

Project description:Na2.22Mn0.87In1.68(PO4)3, sodium manganese indium tris-(phosphate) (2.22/0.87/1.68), was obtained in the form of single crystals by a flux method and was structurally characterized by single-crystal X-ray diffraction. The compound belongs to the alluaudite structure type (space group C2/c) with general formula X(2)X(1)M(1)M(2)2(PO4)3. The X(2) and X(1) sites are partially occupied by sodium [occupancy 0.7676 (17) and 1/2] while the M(1) and M(2) sites are fully occupied within a mixed distribution of sodium/manganese(II) and manganese(II)/indium, respectively. The three-dimensional anionic framework is built up on the basis of M(2)2O10 dimers that share opposite edges with M(1)O6 octa-hedra, thus forming infinite chains extending parallel to [10]. The linkage between these chains is ensured by PO4 tetra-hedra through common vertices. The three-dimensional network thus constructed delimits two types of hexa-gonal channels, resulting from the catenation of M(2)2O10 dimers, M(1)O6 octa-hedra and PO4 tetra-hedra through edge- and corner-sharing. The channels are occupied by Na+ cations with coordination numbers of seven and eight.

Synthesis, spectroscopic, thermal, crystal structure properties, and characterization of new Hofmann-Td-type complexes with 3-aminopyridine.

Project description:In this study, synthesis of two new tetracyanocadmate(II) and tetracyanozincate(II) complexes based on 3-aminopyridine (3AP) and investigation of their structural properties were reported. These complexes were characterized by using vibration spectroscopy, elemental, thermal analysis and single crystal X-ray diffraction (SC-XRD) techniques. Investigation of the elemental, spectral and single crystal data of these complexes showed that the formulas [Cd(3AP)2Zn(μ4-CN)4]n (1) and [Cd(3AP)2Cd(μ4-CN)4]n (2) fully explained their crystal structure. General information about the structural and chemical properties of these complexes obtained in single crystal form was obtained by observing the changes in the characteristic peaks of the 3AP with the [Zn(μ4-CN)4]2- and [Cd(μ4-CN)4]2- structures that make up these complexes. The behaviors of these complexes against changes in temperature were obtained by examining the temperature-dependent changes of their mass. The asymmetric unit of the heterometallic complexes 1 and 2 consist of half Cd(II) ion, half M ion [M = Zn1 in 1 and Cd2 in 2], two cyanide ligands and one 3AP.

Elaboration, structural study and validation of a new NASICON-type structure, Na0.72(Cr0.48,Al1.52)(Mo2.77,Al0.23)O12.

Project description:The title compound, sodium chromium/aluminium molybdenum/aluminium dodeca-oxide, Na0.72Cr0.48Al1.74Mo2.77O12, was prepared by solid-state reaction. Its crystal structure is related to NaSICON-type compounds. The framework is built up from M1O6 (M1 = Cr/Al) octa-hedra and M2O4 (M2 = Mo/Al) tetra-hedra inter-connected by corners. The three-dimensional framework contains cavities in which sodium cations are located. Two validation models (BVS and CHARDI) were used to confirm the proposed structural model. The mobility of Na+ ions in the structure has been investigated by theoretical means.

Coexistence of spin ordering on ladders and spin dimer formation in a new-structure-type compound Sr2Co3S2O3.

Project description:We report on the syntheses and characterizations of single crystalline and polycrystalline Sr2Co3S2O3 with a novel crystal structure type. It contains Co-O 2-leg rectangular ladders and necklace ladders. The two ladders share common legs and construct a hybrid spin ladder. A rare meridional heteroleptic octahedral coordination is found for the Co2+ ions in the 2-leg ladder. Within the necklace ladders, the Co2+ ions are in trans-octahedral coordination. An antiferromagnetic order is observed at TN ~ 267 K, while a broad maximum in magnetic susceptibility is found below TN. This relatively high ordering temperature among Co-based ladder compounds is related to the highly anisotropic mer-coordination of the Co2+ ions. The trans-octahedrally coordinated Co2+ ions, on the other hand, corresponds to the possible short-range magnetic correlations through dimers with an effective . This results in a rare situation that spin ordering and spin dimers coexist down to 2 K.
