Title: Materials Data on Ce4(TmS2)11 by Materials Project

Abstract

Ce4(TmS2)11 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are six inequivalent Tm sites. In the first Tm site, Tm is bonded to seven S atoms to form distorted TmS7 pentagonal bipyramids that share corners with three TmS6 octahedra, edges with two equivalent TmS6 octahedra, and edges with four equivalent TmS7 pentagonal bipyramids. The corner-sharing octahedra tilt angles range from 39–50°. There are a spread of Tm–S bond distances ranging from 2.68–2.87 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 49–59°. There are a spread of Tm–S bond distances ranging from 2.63–2.76 Å. In the third Tm site, Tm is bonded to six S atoms to form TmS6 octahedra that share corners with three equivalent TmS6 octahedra, corners with two equivalent TmS7 pentagonal bipyramids, and edges with four TmS6 octahedra.
