Materials Data on Sm4(LuS2)11 by Materials Project
Abstract
Sm4(LuS2)11 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are six inequivalent Lu3+ sites. In the first Lu3+ site, Lu3+ is bonded to seven S2- atoms to form distorted LuS7 pentagonal bipyramids that share corners with three LuS6 octahedra, edges with two equivalent LuS6 octahedra, and edges with four equivalent LuS7 pentagonal bipyramids. The corner-sharing octahedra tilt angles range from 39–50°. There are a spread of Lu–S bond distances ranging from 2.64–2.83 Å. In the second Lu3+ site, Lu3+ is bonded to six S2- atoms to form a mixture of edge and corner-sharing LuS6 octahedra. The corner-sharing octahedra tilt angles range from 48–59°. There are a spread of Lu–S bond distances ranging from 2.59–2.73 Å. In the third Lu3+ site, Lu3+ is bonded to six S2- atoms to form LuS6 octahedra that share corners with three equivalent LuS6 octahedra, corners with two equivalent LuS7 pentagonal bipyramids, and edges with four LuS6 octahedra. The corner-sharing octahedra tilt angles range from 50–63°. There are a spread of Lu–S bond distances ranging from 2.60–2.74 Å. In the fourth Lu3+ site, Lu3+ is bonded to six S2- atoms to form LuS6 octahedra that share corners with three equivalent LuS6 octahedra,more »
