Title: Materials Data on Tm15S22 by Materials Project

Abstract

Tm15S22 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are eight inequivalent Tm sites. In the first Tm site, Tm is bonded to six S atoms to form TmS6 octahedra that share corners with three equivalent TmS6 octahedra, a cornercorner with one TmS7 pentagonal bipyramid, edges with four equivalent TmS6 octahedra, and edges with two equivalent TmS7 pentagonal bipyramids. The corner-sharing octahedra tilt angles range from 54–60°. There are a spread of Tm–S bond distances ranging from 2.63–2.73 Å. In the second Tm site, Tm is bonded to six S atoms to form a mixture of edge and corner-sharing TmS6 octahedra. The corner-sharing octahedra tilt angles range from 48–59°. There are a spread of Tm–S bond distances ranging from 2.60–2.74 Å. In the third Tm site, Tm is bonded in a 8-coordinate geometry to eight S atoms. There are a spread of Tm–S bond distances ranging from 2.78–2.96 Å. In the fourth Tm site, Tm is bonded to six S atoms to form a mixture of edge and corner-sharing TmS6 octahedra.
