Sr₃ZnPtO₆and Sr₃CdPtO₆

Abstract

The flux synthesis of single crystals of the isostructural compounds tristrontium zinc platinum hexaoxide, Sr(3)ZnPtO(6), and tristrontium cadmium platinum hexaoxide, Sr(3)CdPtO(6), is reported. The compounds adopt the pseudo-one-dimensional rhombohedral K(4)CdCl(6) structure type, and feature chains of face-shared distorted ZnO(6) or CdO(6) trigonal prisms and PtO(6) octahedra, surrounded by columns of Sr(2+) ions. All transition metals are located on the threefold axis of symmetry, while the Sr(2+) cations lie on twofold axes.
