Abstract

The structure of the high-pressure cubic double perovskite Ca₂TiSiO₆ was refined using synchrotron X-ray powder data [S.G. Fm3m, a = 7.4105(1) Å, Z = 4]. Ti and Si are fully ordered into alternating octahedra in the perovskite framework, with Ca occupying a tetrahedrally distorted cuboctahedron. The cation-anion bond lengths are Ti-O = 1.947(3) Å, Si-O = 1.758(3) Å, and Ca-O = 2.622(1) Å.
