Abstract

Er3CuSnS7 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. there are three inequivalent Er3+ sites. In the first Er3+ site, Er3+ is bonded to seven S2- atoms to form distorted ErS7 pentagonal bipyramids that share corners with six ErS7 pentagonal bipyramids, corners with two equivalent SnS4 tetrahedra, edges with four ErS7 pentagonal bipyramids, and an edgeedge with one SnS4 tetrahedra. There are a spread of Er–S bond distances ranging from 2.70–3.03 Å. In the second Er3+ site, Er3+ is bonded to seven S2- atoms to form distorted ErS7 pentagonal bipyramids that share corners with six ErS7 pentagonal bipyramids, corners with two equivalent SnS4 tetrahedra, edges with four ErS7 pentagonal bipyramids, and an edgeedge with one SnS4 tetrahedra. There are a spread of Er–S bond distances ranging from 2.70–3.03 Å.
