Materials Data on Tm3CrS6 by Materials Project
Abstract
Tm3CrS6 crystallizes in the orthorhombic Pnnm space group. The structure is three-dimensional. there are three inequivalent Tm3+ sites. In the first Tm3+ site, Tm3+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are a spread of Tm–S bond distances ranging from 2.73–2.89 Å. In the second Tm3+ site, Tm3+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are a spread of Tm–S bond distances ranging from 2.72–3.05 Å. In the third Tm3+ site, Tm3+ is bonded to seven S2- atoms to form distorted TmS7 pentagonal bipyramids that share a cornercorner with one CrS6 octahedra, edges with two equivalent CrS6 octahedra, and edges with two equivalent TmS7 pentagonal bipyramids. The corner-sharing octahedral tilt angles are 35°. There are a spread of Tm–S bond distances ranging from 2.69–2.83 Å. There are two inequivalent Cr3+ sites. In the first Cr3+ site, Cr3+ is bonded to six S2- atoms to form CrS6 octahedra that share edges with two equivalent CrS6 octahedra and edges with four equivalent TmS7 pentagonal bipyramids. There are two shorter (2.41 Å) and four longer (2.44 Å) Cr–S bond lengths. In the second Cr3+ site, Cr3+ is bonded to six S2- atoms to form CrS6more »
