Materials Data on Sr2CdWO6 by Materials Project

Abstract

Sr2CdWO6 is Orthorhombic Perovskite-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Sr2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Sr–O bond distances ranging from 2.50–2.95 Å. W6+ is bonded to six O2- atoms to form WO6 octahedra that share corners with six equivalent CdO6 octahedra. The corner-sharing octahedra tilt angles range from 27–31°. All W–O bond lengths are 1.96 Å. Cd2+ is bonded to six O2- atoms to form CdO6 octahedra that share corners with six equivalent WO6 octahedra. The corner-sharing octahedra tilt angles range from 27–31°. There are a spread of Cd–O bond distances ranging from 2.31–2.35 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent Sr2+, one W6+, and one Cd2+ atom. In the second O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent Sr2+, one W6+, and one Cd2+ atom. In the third O2- site, O2- is bonded to two equivalent Sr2+, one W6+, and one Cd2+ atom to form distorted corner-sharing OSr2CdW tetrahedra.
