Materials Data on SrNi5P3 by Materials Project

Abstract

SrNi5P3 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Sr2+ is bonded in a 7-coordinate geometry to seven P3- atoms. There are a spread of Sr–P bond distances ranging from 3.10–3.26 Å. There are three inequivalent Ni+1.40+ sites. In the first Ni+1.40+ site, Ni+1.40+ is bonded to four P3- atoms to form a mixture of edge and corner-sharing NiP4 tetrahedra. There are a spread of Ni–P bond distances ranging from 2.26–2.35 Å. In the second Ni+1.40+ site, Ni+1.40+ is bonded to four P3- atoms to form a mixture of edge and corner-sharing NiP4 tetrahedra. There are a spread of Ni–P bond distances ranging from 2.19–2.37 Å. In the third Ni+1.40+ site, Ni+1.40+ is bonded in a square co-planar geometry to four equivalent P3- atoms. All Ni–P bond lengths are 2.32 Å. There are two inequivalent P3- sites. In the first P3- site, P3- is bonded in a 9-coordinate geometry to three equivalent Sr2+ and six Ni+1.40+ atoms. In the second P3- site, P3- is bonded in a 9-coordinate geometry to two equivalent Sr2+ and seven Ni+1.40+ atoms.
