Materials Data on Ce2CuBiS5 by Materials Project
Abstract
Ce2CuBiS5 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Ce3+ sites. In the first Ce3+ site, Ce3+ is bonded in a 7-coordinate geometry to eight S2- atoms. There are a spread of Ce–S bond distances ranging from 2.94–3.45 Å. In the second Ce3+ site, Ce3+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are a spread of Ce–S bond distances ranging from 2.96–3.11 Å. Cu1+ is bonded to four S2- atoms to form distorted CuS4 trigonal pyramids that share corners with three equivalent BiS6 octahedra, corners with two equivalent CuS4 trigonal pyramids, and edges with two equivalent CuS4 trigonal pyramids. The corner-sharing octahedra tilt angles range from 11–83°. There are a spread of Cu–S bond distances ranging from 2.28–2.55 Å. Bi3+ is bonded to six S2- atoms to form BiS6 octahedra that share corners with three equivalent CuS4 trigonal pyramids and edges with two equivalent BiS6 octahedra. There are a spread of Bi–S bond distances ranging from 2.72–2.93 Å. There are five inequivalent S2- sites. In the first S2- site, S2- is bonded to four Ce3+ and one Cu1+ atom to form distorted SCe4Cu trigonal bipyramids that share corners withmore »
