inorganic compounds

 

CeMo₈O₁₄, a Third Crystalline Form of the RMo₈O₁₄ Series (R = La, Ce, Pr, Nd, Sm)

G. Kerihuel and P. Gougeon

Synopsis: The structure of CeMo₈O₁₄ contains an equal mixture of cis-edge-sharing and trans bicapped octahedral Mo₈ clusters arranged in layers. The oxygen framework derives from close-packed layers with the sequence ABAC. The Ce³⁺ ions are surrounded by 12 O atoms forming a distorted cuboctahedron.

Formula: CeMo₈O₁₄

 

Structure Refinement of Y₂Ru₂O₇ by Neutron Powder Diffraction

B. J. Kennedy

Synopsis: The structure of the pyrochlore Y₂Ru₂O₇ was determined by Rietveld analysis of time-of-flight neutron powder diffraction data. Each Ru atom has a nearly regular octahedral coordination environment whereas each Y atom has distorted eightfold coordination geometry.

Formula: Y₂Ru₂O₇

 

Structure Refinement of Orthorhombic MnAl₃

V. V. Pavlyuk, T. I. Yanson, O. I. Bodak, R. Cerný, R. E. Gladyshevskii, K. Yvon and J. Stepien-Damm

Synopsis: Structure refinements of Mn₃Al₁₀ were performed in the space groups Pnma and Pn2₁a. All atom sites in Pn2₁a were within 3 from those in Pnma, except for three Al positions, which were within 6. The space group Pnma was found to be correct.

Formula: Mn_3.01(6)Al_9.99(6)

 

Silicatoniobate de Potassium, K₃Nb₃O₆Si₂O₇

S. Jaulmes, S. Launay, P. Mahé and M. Quarton

Synopsis: The structure of K₃Nb₃O₆Si₂O₇ is built up from Si₂O₇ ditetrahedra and groups of three corner-linked NbO₆ octahedra. The framework is isotypic with that of Ba₃Nb₆O₁₂(Si₂O₇)₂, but the filling of the tunnels with K⁺ ions rather than Ba²⁺ ions determines the space group to be P\=62c.

Formula: K₃Nb₃O₆Si₂O₇

 

CaV₂O(PO₄)₂, Isotypic with the Cd Phase

S. Boudin, A. Grandin, A. Leclaire, M.-M. Borel and B. Raveau

Synopsis: The structure of this new vanadium(III) monophosphate contains [VO₄] rutile chains and VPO₈ units, each formed from a VO₆ octahedron sharing an edge with a PO₄ tetrahedron.

Formula: CaV₂O(PO₄)₂

 

Hydroxylammonium Sulfate

A. Mirceva and L. Golic

Synopsis: The structure of (NH₃OH)₂SO₄ consists of sulfate and hydroxylammonium ions, which are connected by O-HO and N-HO hydrogen bonds. All O atoms of the sulfate groups are involved in two hydrogen bonds.

Formula: (NH₃OH)₂SO₄
