Cs₆[Mo₇O₂₄].7H₂O

U. Kortz and M. T. Pope

Synopsis: The structure of Cs₆[Mo₇O₂₄].7H₂O contains 9- 10- and 11-coordinate Cs⁺ cations bound to terminal, doubly bridging and quadruply bridging O atoms of the polyanions, as well as to water molecules.

Formula: Cs₆[Mo₇O₂₄].7H₂O

U. Peuchert, L. Bohatý and R. Fröhlich

Synopsis: Substitution of 2Ti⁴⁺ in the structure of KTiOPO₄ (KTP) by Ni²⁺ and W⁶⁺ leads to the new non-centrosymmetric compound K₂NiWO₂(PO₄)₂ (KNiWP). The structures of KTP and KNiWP are closely related.

Formula: K₂NiWO₂(PO₄)₂

P. Becker, L. Bohatý and R. Fröhlich

Synopsis: The crystal structure of CsNbOB₂O₅ represents the basic structure type of the borate family AMOB₂O₅ with A = K, Rb, Cs, Tl and M = Nb, Ta. The structure contains untilted chains of [NbO₆] octahedra linked by planar [B₂O₅] groups. Cs is coordinated irregularly by eight O atoms.

Formula: CsNbOB₂O₅

 

SrTa₄O₁₁: a Rietveld Refinement Using Neutron Powder Diffraction Data

G. W. J. C. Heunen, D. J. W. IJdo and R. B. Helmholdt

Synopsis: The structure of SrTa₄O₁₁ contains layers of TaO₇ pentagonal bipyramids sharing edges, as found in U₃O₈. Between the layers lie Sr atoms with distorted cubic coordination geometry and Ta atoms with distorted octahedral coordination geometry.

Formula: SrTa₄O₁₁

 

Two New Scandium Phases: ScSn₂ and Sc₆Pb₅

M. Pani, P. Manfrinetti and M. L. Fornasini

Synopsis: The structure of ScSn₂ is related to the ZrSi₂ structure type and contains slabs of Sc trigonal prisms centred by Sn. Sc₆Pb₅, isotypic with Ti₆Ge₅, is characterized by infinite columns of Sc tetragonal antiprisms centred by Pb and by infinite columns of Pb octahedra centred by Sc atoms.

Formula: ScSn₂ and Sc₆Pb₅

 

Synthetic Dipotassium Zinc Disilicate

A. R. Hogrefe and M. Czank

Synopsis: The outstanding features of this new vierer single-chain silicate are the large stretching factor of the silicate chain of f_s = 96.8%, a very small Si-O-Si angle of 118.3° and the presence of three-membered rings formed from two [SiO₄] and one [ZnO₄] tetrahedra.

Formula: K₄Zn₂Si₄O₁₂

 

Paraelastic Pb₅Al₃F₁₉ at 370 K

S. Sarraute, J. Ravez, G. Bravic, D. Chasseau and S. C. Abrahams

Formula: Pb₅Al₃F₁₉

 

Octachlorosilasesquioxane, Cl₈Si₈O₁₂

K. W. Törnroos, G. Calzaferri and R. Imhof

Synopsis: The cage compound Cl₈Si₈O₁₂ shows a close structural resemblance to the compound (CH₃)₈Si₈O₁₂. As a result of interelectronic repulsion and the considerable electronegativity of the Cl substituent, distortions of the tetrahedral Si environment and a shortening of the Si-O bond occur.

Formula: Cl₈Si₈O₁₂

Formula: Li_1.14Nb_0.93Sc_0.67Cr_0.40P₃O₁₂

 

Lead(II) Hydrogenselenite

M. Koskenlinna and J. Valkonen
