Materials Data on Cd2SnO4 by Materials Project
Cd2SnO4 crystallizes in the orthorhombic Pbam space group. The structure is three-dimensional. Cd2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Cd–O bond distances ranging from 2.30–2.47 Å. Sn4+ is bonded to six O2- atoms to form edge-sharing SnO6 octahedra. There are two shorter (2.08 Å) and four longer (2.14 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 OCd2Sn2 trigonal pyramids that share corners with eight equivalent OCd4Sn trigonal bipyramids, corners with four equivalent OCd2Sn2 trigonal pyramids, edges with two equivalent OCd4Sn trigonal bipyramids, and edges with two equivalent OCd2Sn2 trigonal pyramids. In the second O2- site, O2- is bonded to four equivalent Cd2+ and one Sn4+ atom to form distorted OCd4Sn trigonal bipyramids that share corners with five equivalent OCd4Sn trigonal bipyramids, corners with eight equivalent OCd2Sn2 trigonal pyramids, edges with four equivalent OCd4Sn trigonal bipyramids, and edges with two equivalent OCd2Sn2 trigonal pyramids.
