Ce₂₀Mg₁₉Zn₈₁: a new structure type with a giant cubic cell

V. Pavlyuk, P. Solokha, O. Zelinska, V. Paul-Boncour and A. Nowik-Zajac

Synopsis: Ce₂₀Mg₁₉Zn₈₁ is a new structure type for rare earth-transition metal-magnesium intermetallic compounds, with a large cubic unit cell containing 480 atoms. Four different construction units following the geometric concept of nested polyhedral units are identified to simplify the structure.

The new pentaborate Na₃SrB₅O₁₀

L. Wu, G. Roth, K. Sparta and X. Chen

Synopsis: The fundamental building unit for the title compound is the isolated anionic [B₅O₁₀]^5- group. The local mm2 point symmetry of the ideal B₅O₁₀ group is broken, as the terminal O atoms have a small deviation from the corresponding six-membered ring planes.

N. Jennene Boukharrata, J.-P. Laval and P. Thomas

Synopsis: The crystal structures of the new phases ScTeO₃F and InTeO₃F belong to two different structural types that also differ from that of the recently published series MTeO₃F (M = Fe, Ga and Cr). A comparison is made of the three MTeO₃F types.

A new type of mixed anionic framework in microporous rubidium copper vanadyl(V) phosphate, Rb₂Cu(VO₂)₂(PO₄)₂

O. V. Yakubovich, I. M. Steele and O. V. Dimitrova

Synopsis: Crystals of of Rb₂Cu(VO₂)₂(PO₄)₂ have a novel structure type with a porous mixed framework formed by Cu, V and P oxo complexes. VO₅ polyhedra in a trigonal bipyramidal configuration and PO₄ tetrahedra share vertices to form eight-membered rings, which lie in layers perpendicular to the a axis of the monoclinic unit cell. Cu atoms at centres of symmetry have square-planar coordination and link these layers along [100] to form a three-dimensional anionic framework.
