Crystal structure of the deuterated heptahydrate of potassium phosphate, K3PO4·7D2O.

ABSTRACT: Deuterated potassium orthophosphate heptahydrate, K3PO4·7D2O, crystallizes in the Sohnke space group P21, and its absolute structure was determined from 2017 Friedel pairs [Flack parameter 0.004?(16)]. Each of the three crystallographically unique K+ cations is surrounded by six water molecules and one oxygen atom from the orthophosphate group, using a threshold for K—O bonds of 3.10?Å. The highly irregular coordination polyhedra are linked by corner- and edge-sharing into a three-dimensional network that is consolidated by an intricate network of O—D?O hydrogen bonds of medium strength.

Crystal structure of hepta-guanidinium nona-hydrogen bis-[?-hexa-molybdoplatinate(IV)] hepta-hydrate.

Project description:The title compound, (CH6N3)7H9[PtMo6O24]2·7H2O, containing the well-known Anderson-type heteropolyoxomolybdate, was obtained by recrystallization of its powdered guanidinium salt. The protonated O atoms in the polyanion were confirmed by electron-density maps, inter-polyanion hydrogen bonds and bond-valance sums (BVS). The {[H4.5PtMo6O24]2}(7-) polyanion is the same as that already characterized in K7[H4.5PtMo6O24]2·11H2O [space group P-1; Lee & Joo (2010 ?). Acta Cryst. E66, i8-i9]. The heteropolyanions form inversion-generated dimers, {[H4.5PtMo6O24]2}(7-), held together by each of the four ?3-O-H??1-O, two ?2-O-H??2-O hydrogen bonds and one centrosymmetric ?3-O-H-?3-O hydrogen bond. The H atom of the centrosymmetric hydrogen bond is located on an inversion centre. One guanidinium ion and one water mol-ecule are equally disordered about a twofold rotation axis.

Crystal structure of potassium sodium hepta-hydrogen hexa-molybdocobaltate(III) octa-hydrate: an extra-protonated B-series Anderson-type heteropolyoxidometalate.

Project description:The title compound, KNa[Co(III)(OH)7{Mo6O17}]·8H2O, was obtained by the ion-exchange technique from K3[Co(μ3-OH)6Mo6O18]·7H2O. Six μ3-O atoms and one O atom of the bridging μ2-O atom are protonated. This novel polyanion protonated by an extra H atom is an unexpected polyanion species among the B-series Anderson-type polyoxidometalates (POMs), [X(n) (+)(μ3-OH)6Mo6O18]((6-n)-)] (X = heteroatom). The extra H atom (seventh H atom) in the polyanion does not lie on a crystallographic centre of symmetry, but is located at the mid-point between two μ2-O atoms of adjacent polyanions, and forms a very short hydrogen bond [2.430 (5) Å]. The present structure is considered as particularly significant in understanding noncentrosymmetric strong hydrogen bonding.

Crystal structure of magnesium selenate hepta-hydrate, MgSeO4·7H2O, from neutron time-of-flight data.

Project description:MgSeO4·7H2O is isostructural with the analogous sulfate, MgSO4·7H2O, consisting of isolated [Mg(H2O)6](2+) octa-hedra and [SeO4](2-) tetra-hedra, linked by O-H?O hydrogen bonds, with a single inter-stitial lattice water mol-ecule. As in the sulfate, the [Mg(H2O)6](2+) coordination octa-hedron is elongated along one axis due to the tetra-hedral coordination of the two apical water mol-ecules; these have Mg-O distances of ?2.10?Å, whereas the remaining four trigonally coordinated water mol-ecules have Mg-O distances of ?2.05?Å. The mean Se-O bond length is 1.641?Å and is in excellent agreement with other selenates. The unit-cell volume of MgSeO4·7H2O at 10?K is 4.1% larger than that of the sulfate at 2?K, although this is not uniform; the greater part of the expansion is along the a axis of the crystal.

Redetermination of hepta-potassium nona-hydrogen bis-[?-hexa-molybdoplatinate(IV)] undeca-hydrate.

Project description:Previously reported at a temperature of 298?(2)?K [Lee & Joo (2007 ?). Acta Cryst. E63, i11-i13], the title compound, K(7)[H(9)?-Pt(2)Mo(12)O(48)]·11H(2)O or K(7)[H(4.5)?-PtMo(6)O(24)](2)·11H(2)O, was redetermined at 146?(2)?K in order to determine whether the H atom in the hydrogen bond that crosses the center of symmetry was located at the center of symmetry or disordered around it as assumed in the previous study. During the present low-temperature study it was found on the center of symmetry. One water molecule shows half-occupancy.

Crystal structure of (18-crown-6)potassium(I) [(1,2,3,4,5-?)-cyclo-hepta-dien-yl][(1,2,3-?)-cyclo-hepta-trien-yl]cobalt(I).

Project description:The reaction of bis-(anthracene)cobaltate(-I) with excess cyclo-hepta-triene, C7H8, resulted in a new 18-electron cobaltate containing two different seven-membered ring ligands, based on single-crystal X-ray diffraction. The asymmetric unit of this structure contains two independent cation-anion pairs of the title complex, [K(18-crown-6)][Co(?(3)-C7H7)(?(5)-C7H9)], where 18-crown-6 stands for 1,4,7,10,13,16-hexa-oxa-cyclo-octa-decane (C12H24O6), in general positions and well separated. Each (18-crown-6)potassium cation is in contact with the ?(3)-coordinating ligand of one cobaltate complex. Each ?(3)-coordinating ligand behaves as an allylic anion whose exo-diene moiety is bent away from the allylic plane, and thus is not involved directly in the bonding. The metal-coordinating portions of the anionic ?(5) ligands are planar and one of these ligands is modeled as disordered over two positions, with occupancy ratio 0.699?(5):0.301?(5), such that one orientation is rotated by one carbon atom with respect to the other. The diffraction intensities were integrated according to non-merohedral twin law [-1 0 0/0 -1 0/0.064 0 1], a 180° rotation about reciprocal lattice axis [001], and the masses of the twin domains refined to equal amounts. As both ligands are formally coordinated as anions, the cobalt atom is best considered to be Co(I). This compound is of inter-est as the first to possess cyclo-hepta-trienyl and cyclo-hepta-dienyl ligands in an anionic metal complex.

Determination of the Raman polarizability tensor in the optically anisotropic crystal potassium dihydrogen phosphate and its deuterated analog.

Project description:The Raman tensor of the dominant A1 modes of the nonlinear optical crystalline material potassium dihydrogen phosphate and its 70% deuterated analog have been ascertained. Challenges in determining the A1 mode tensor element values based on previous reports have been resolved using a specially designed experimental setup that makes use of spherical crystal samples. This novel experimental design enabled the determination of measurement artifacts, including polarization rotation of the pump and/or scattered light propagating through the sample and the contribution of additional overlapping phonon modes, which have hindered previous efforts. Results confirmed that the polarization tensor is diagonal, and matrix elements were determined with high accuracy.

Crystal structure of disodium 2-amino-6-oxo-6,7-di-hydro-1H-purine-1,7-diide hepta-hydrate.

Project description:In the title compound, disodium 2-amino-6-oxo-6,7-di-hydro-1H-purine-1,7-diide hepta-hydrate, 2Na(+)·C5H3N5O(2-)·7H2O, the structure is composed of alternating (100) layers of guanine mol-ecules and hydrated Na(+) ions. Within the guanine layer, the mol-ecules are arranged in centrosymmetric pairs, with a partial overlap between the guanine rings. In this compound, guanine exists as the amino-keto tautomer from which deprotonation from N1 and N7 has occurred (purine numbering). There are no direct inter-actions between the Na(+) cations and the guanine anions. Guanine mol-ecules are linked to neighboring water mol-ecules by O-H?N and O-H?O hydrogen bonds into a network structure.

Crystal structure of penta-potassium di-hydrogen nona-vanadato(V)platinate(IV) nona-hydrate.

Project description:The title compound, K5[H2PtV9O28]·9H2O, containing the nona-vanado-platinate(IV) polyanion, was obtained by hydro-thermal reaction at pH = 4.2. The polyanion has approximate mm2 (C 2v ) symmetry. The two platinum-bound ?2-O atoms are protonated in the polyanion. The heteropolyanions form inversion-generated dimers, {[H2PtV9O28]2}(10-), held together by ?2-O-H??2-O and ?2-O-H??3-O hydrogen bonds. All K(+) cations are located on general positions of the space group P-1.

Diterbium hepta-nickel: a crystal structure redetermination.

Project description:The crystal structure of the title compound, Tb2Ni7, was redetermined from single-crystal X-ray diffraction data. In comparison with previous studies based on powder X-ray diffraction data [Lemaire et al. (1967). C. R. Acad. Sci. Ser. B, 265, 1280-1282; Lemaire & Paccard (1969). Bull. Soc. Fr. Mineral. Cristallogr. 92, 9-16; Buschow & van der Goot (1970). J. Less-Common Met. 22, 419-428], the present redetermination affords refined coordinates and anisotropic displacement parameters for all atoms. A partial occupation for one Tb atom results in the non-stoichiometric composition Tb1.962?(4)Ni7. The title compound adopts the Ce2Ni7 structure type and can also be derived from the CaCu5 structure type as an inter-growth structure. The asymmetric unit contains two Tb sites (both site symmetries 3m.) and five Ni sites (.m., mm2, 3m., 3m., -3m.). The two different coordination polyhedra of Tb are a Frank-Kasper polyhedron formed by four Tb and 12 Ni atoms and a pseudo Frank-Kasper polyhedron formed by two Tb and 18 Ni atoms. The four different coordination polyhedra of Ni are Frank-Kasper icosa-hedra formed by five Tb and seven Ni atoms, four Tb and eight Ni atoms, three Tb and nine Ni atoms, and six Tb and six Ni atoms, respectively.

Crystal structure of undeca-potassium bis-[α-hemi-penta-hydrogen hexa-molybdoplatinate(IV)] dodeca-hydrate.

Project description:The title compound, K11[α-Pt(μ3-OH)2(μ3-OH0.5)Mo6(μ3-O)3(μ2-O)6O12]2·12H2O (simplified chemical formula K11[H2.5PtMo6O24]2·12H2O), containing the well-known Anderson-type heteropolyoxomolybdate anion, was obtained by hydro-thermal reaction at pH = ca 6.0. The complete polyanion dimer has 2/m symmetry. The locations of the H atoms with respect to protonated O atoms were obtained from difference Fourier maps, and confirmed by the inter-polyanion hydrogen bonds, bond-length elongation and bond-valence sums (BVSs). The title heteropolyanion has two types of protonated O atoms viz. μ3-OH, {Mo2-O(H)-Pt} and μ3-OH0.5 (disordered H atom). The [H2.5α-PtMo6O24](5.5-) polyanion forms a dimer, [(H2.5α-PtMo6O24)2](11-), held together by two pairs of μ3-O-H⋯μ1-O and of one disordered μ3-O⋯H⋯μ3-O hydrogen bonds. Three K(+) ions are located on special positions (two on twofold rotation axes, one on a mirror plane), and two K(+) ions are located on general positions with a reduced occupancy of 0.5. The remaining K(+) ion has a reduced occupancy of 0.25 for charge balance and reasonable displacement parameters. As a result, the numbers of K(+) and H(+) ions in the title compound are 5.5 and 2.5, respectively.
