Materials Data on CdSnP14 by Materials Project

Abstract

CdSnP14 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Cd2+ is bonded in a tetrahedral geometry to four P+0.29- atoms. There are three shorter (2.62 Å) and one longer (2.72 Å) Cd–P bond lengths. Sn2+ is bonded in a distorted square co-planar geometry to four P+0.29- atoms. There are a spread of Sn–P bond distances ranging from 2.71–2.97 Å. There are nine inequivalent P+0.29- sites. In the first P+0.29- site, P+0.29- is bonded in a trigonal non-coplanar geometry to three P+0.29- atoms. There are a spread of P–P bond distances ranging from 2.21–2.30 Å. In the second P+0.29- site, P+0.29- is bonded to one Cd2+, one Sn2+, and two equivalent P+0.29- atoms to form distorted corner-sharing PCdSnP2 tetrahedra. In the third P+0.29- site, P+0.29- is bonded in a trigonal non-coplanar geometry to three P+0.29- atoms. There are one shorter (2.21 Å) and one longer (2.23 Å) P–P bond lengths. In the fourth P+0.29- site, P+0.29- is bonded in a trigonal non-coplanar geometry to three P+0.29- atoms. There are two shorter (2.23 Å) and one longer (2.24 Å) P–P bond lengths. In the fifth P+0.29- site, P+0.29- is bonded in a trigonal non-coplanar geometry to three P+0.29- atoms. Both P–P bond lengths are 2.22 Å. In the sixth P+0.29- site, P+0.29- is bonded in a trigonal non-coplanar geometry to three P+0.29- atoms. The P–P bond length is 2.20 Å. In the seventh P+0.29- site, P+0.29- is bonded to one Cd2+, one Sn2+, and two equivalent P+0.29- atoms to form distorted corner-sharing PCdSnP2 tetrahedra. In the eighth P+0.29- site, P+0.29- is bonded in a trigonal non-coplanar geometry to three P+0.29- atoms. The P–P bond length is 2.20 Å. In the ninth P+0.29- site, P+0.29- is bonded to one Cd2+, one Sn2+, and two P+0.29- atoms to form distorted corner-sharing PCdSnP2 tetrahedra.
