Cs₆[Mo₇O₂₄].7H₂O

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.

K₂NiWO₂(PO₄)₂: a New Structure Type Related to KTiOPO₄ (KTP)

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.

CsNbOB₂O₅: the Basic Structure Type of the Borates AMOB₂O₅ (A = K, Rb, Cs, Tl; M = Nb, Ta)

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.

SrTa₄O₁₁: a Rietveld Refinement Using Neutron Powder Diffraction Data

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.

Two New Scandium Phases: ScSn₂ and Sc₆Pb₅

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.

Synthetic Dipotassium Zinc Disilicate

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.

Paraelastic Pb₅Al₃F₁₉ at 370 K

Pb₅Al₃F₁₉ undergoes three phase transitions between 80 and 400K. The structure at 370K contains corner-sharing AlF₆ octahedra and individual AlF₆ octahedra. The Pb atoms occupy tunnels of 2.5Å radii.

Octa­chlorosilasesquioxane, Cl₈Si₈O₁₂

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.

Li_1.14Nb_0.93Sc_0.67Cr_0.40(PO₄)₃

Li_1.14Nb_0.93Sc_0.67Cr_0.40P₃O₁₂ is the first example of a Nasicon-type compound containing a pentavalent cation. The [M₂(PO₄)₃] framework contains double [M(1)M(2)P₃O₁₈] units which share apical O atoms to form a three-dimensional network.

Lead(II) Hydrogenselenite

The structure of Pb(HSeO₃)₂ consists of layers of Pb-O polyhedra and selenite groups. The coordination polyhedron of Pb is a square antiprism.

Re-Examination Shows that Copper(II) Tetra­chloroaluminium, Cu(AlCl₄)₂, is Monoclinic and not Triclinic as Originally Stated

Analysis of previously published diffraction data shows that Cu(AlCl₄)₂ is monoclinic. Refinement on this basis gives an improved R factor. The changes in the structure are small.
