Materials Data on CdSnO3 by Materials Project

Abstract

CdSnO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Cd2+ is bonded in a 4-coordinate geometry to eight O2- atoms. There are a spread of Cd–O bond distances ranging from 2.28–2.88 Å. Sn4+ is bonded to six O2- atoms to form corner-sharing SnO6 octahedra. The corner-sharing octahedra tilt angles range from 36–38°. There are four shorter (2.09 Å) and two longer (2.13 Å) Sn–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Cd2+ and two equivalent Sn4+ atoms to form distorted corner-sharing OCd2Sn2 tetrahedra. In the second O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent Cd2+ and two equivalent Sn4+ atoms.
