Rb₄Zr₃Te₁₆, a one-dimensional zirconium telluride synthesized from molten salt

A. B. Anderson, R.-J. Wang and J. Li

Synopsis: The crystal structure of Rb₄Zr₃Te₁₆ consists of infinite one-dimensional chains of [Zr₃Te₁₆]_n^4n- separated from each other by Rb⁺ cations. Within the chain, each Zr atom is surrounded by eight Te atoms to give a distorted bicapped trigonal prism polyhedron.

Formula: Rb₄Zr₃Te₁₆

Synopsis: The Schiff base ligand in the title complex is deprotonated with respect to its tautomeric thiol form and is coordinated to the Pt^II atom via the mercapto-S and [beta] -N atoms. The Pt^II coordination is square planar. The phenyl ring of the ligand is twisted out of the coordination plane by 31.8 (2)° due to the steric effect of the Br atom.

Bis(2,2'-bipyridyl-N,N')tris(nitrato-O,O')neodymium

J. F. Bower, S. A. Cotton, J. Fawcett and D. R. Russell

Synopsis: The title compound is isomorphous with the La and Lu analogues having three bidentate nitrate and two bipyridyl ligands, giving the metal atom a ten-coordinate bicapped dodecahedral environment. The average Nd-N and Nd-O bond lengths (2.596 and 2.549 Å, respectively) are shorter than the corresponding bonds of the La analogue reflecting the smaller ionic radius of neodymium. There is evidence that the non-coordinating O atom of the nitrate group lying formally on a crystallographic twofold axis is disordered on either side of the axis.
