Materials Data on FeCu5S4 by Materials Project
Abstract
Cu5FeS4 crystallizes in the trigonal R3m space group. The structure is three-dimensional. Fe3+ is bonded to four S2- atoms to form FeS4 tetrahedra that share corners with six equivalent FeS4 tetrahedra, corners with nine CuS4 tetrahedra, and edges with three equivalent CuS4 tetrahedra. There are one shorter (2.21 Å) and three longer (2.36 Å) Fe–S bond lengths. There are five inequivalent Cu1+ sites. In the first Cu1+ site, Cu1+ is bonded to four S2- atoms to form a mixture of corner and edge-sharing CuS4 tetrahedra. There are one shorter (2.27 Å) and three longer (2.43 Å) Cu–S bond lengths. In the second Cu1+ site, Cu1+ is bonded in a trigonal planar geometry to three equivalent S2- atoms. All Cu–S bond lengths are 2.22 Å. In the third Cu1+ site, Cu1+ is bonded to four S2- atoms to form CuS4 tetrahedra that share corners with three equivalent FeS4 tetrahedra, corners with nine CuS4 tetrahedra, edges with three equivalent FeS4 tetrahedra, and edges with three equivalent CuS4 tetrahedra. There are one shorter (2.32 Å) and three longer (2.43 Å) Cu–S bond lengths. In the fourth Cu1+ site, Cu1+ is bonded to four S2- atoms to form CuS4 tetrahedra that share corners withmore »
