Materials Data on NaCr(PS3)2 by Materials Project

Abstract

NaCr(PS3)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Na1+ is bonded in a 6-coordinate geometry to six S2- atoms. There are a spread of Na–S bond distances ranging from 2.89–3.45 Å. Cr3+ is bonded to six S2- atoms to form edge-sharing CrS6 octahedra. There are a spread of Cr–S bond distances ranging from 2.41–2.45 Å. There are two inequivalent P4+ sites. In the first P4+ site, P4+ is bonded in a trigonal non-coplanar geometry to three S2- atoms. There are a spread of P–S bond distances ranging from 1.98–2.13 Å. In the second P4+ site, P4+ is bonded in a trigonal non-coplanar geometry to three S2- atoms. There are a spread of P–S bond distances ranging from 1.98–2.14 Å. There are six inequivalent S2- sites. In the first S2- site, S2- is bonded in a trigonal non-coplanar geometry to two equivalent Cr3+ and one P4+ atom. In the second S2- site, S2- is bonded in a distorted T-shaped geometry to one Na1+, one Cr3+, and one P4+ atom. In the third S2- site, S2- is bonded in a 4-coordinate geometry to three equivalent Na1+ and one P4+ atom. In the fourth S2- site, S2- is bonded in a water-like geometry to one Cr3+ and one P4+ atom. In the fifth S2- site, S2- is bonded in a trigonal non-coplanar geometry to two equivalent Cr3+ and one P4+ atom. In the sixth S2- site, S2- is bonded in a 3-coordinate geometry to two equivalent Na1+ and one P4+ atom.
