Materials Data on Tm4MnS7 by Materials Project
Abstract
Tm4MnS7 crystallizes in the monoclinic Cm space group. The structure is three-dimensional. there are four inequivalent Tm3+ sites. In the first Tm3+ site, Tm3+ is bonded to seven S2- atoms to form distorted TmS7 pentagonal bipyramids that share corners with four TmS6 octahedra, corners with four equivalent MnS6 octahedra, an edgeedge with one MnS6 octahedra, edges with three equivalent TmS6 octahedra, edges with two equivalent TmS7 pentagonal bipyramids, and faces with two equivalent TmS7 pentagonal bipyramids. The corner-sharing octahedra tilt angles range from 19–73°. There are a spread of Tm–S bond distances ranging from 2.69–3.02 Å. In the second Tm3+ site, Tm3+ is bonded to seven S2- atoms to form distorted TmS7 pentagonal bipyramids that share corners with two equivalent MnS6 octahedra, corners with six TmS6 octahedra, edges with four TmS6 octahedra, edges with two equivalent TmS7 pentagonal bipyramids, and faces with two equivalent TmS7 pentagonal bipyramids. The corner-sharing octahedra tilt angles range from 22–68°. There are a spread of Tm–S bond distances ranging from 2.68–2.95 Å. In the third Tm3+ site, Tm3+ is bonded to six S2- atoms to form TmS6 octahedra that share a cornercorner with one TmS6 octahedra, a cornercorner with one MnS6 octahedra, corners with fourmore »
