Materials Data on SnHgP14 by Materials Project
HgSnP14 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Hg2+ is bonded in a trigonal pyramidal geometry to four P+0.29- atoms. There are a spread of Hg–P bond distances ranging from 2.59–2.77 Å. 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 2.69–2.97 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 2.22–2.30 Å. In the second P+0.29- site, P+0.29- is bonded to one Hg2+, one Sn2+, and two equivalent P+0.29- atoms to form corner-sharing PSnHgP2 tetrahedra. Both P–P bond lengths are 2.21 Å. 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 (2.20 Å) and one longer (2.22 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. The P–P bond length is 2.25 Å. In the fifth 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 (2.20 Å) and two longer (2.22 Å) P–P bond lengths. In the sixth P+0.29- site, P+0.29- is bonded to one Hg2+, one Sn2+, and two P+0.29- atoms to form corner-sharing PSnHgP2 tetrahedra. In the seventh P+0.29- site, P+0.29- is bonded in a trigonal non-coplanar geometry to three P+0.29- atoms. In the eighth P+0.29- site, P+0.29- is bonded in a trigonal non-coplanar geometry to three P+0.29- atoms. In the ninth P+0.29- site, P+0.29- is bonded to one Hg2+, one Sn2+, and two equivalent P+0.29- atoms to form corner-sharing PSnHgP2 tetrahedra.
