Materials Data on Cu9S5 by Materials Project

Abstract

Cu9S5 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are nine inequivalent Cu+1.11+ sites. In the first Cu+1.11+ site, Cu+1.11+ is bonded to four S2- atoms to form a mixture of edge and corner-sharing CuS4 tetrahedra. There are a spread of Cu–S bond distances ranging from 2.34–2.41 Å. In the second Cu+1.11+ site, Cu+1.11+ is bonded to four S2- atoms to form a mixture of edge and corner-sharing CuS4 tetrahedra. There are a spread of Cu–S bond distances ranging from 2.35–2.40 Å. In the third Cu+1.11+ site, Cu+1.11+ is bonded to four S2- atoms to form a mixture of edge and corner-sharing CuS4 tetrahedra. There are two shorter (2.35 Å) and two longer (2.40 Å) Cu–S bond lengths. In the fourth Cu+1.11+ site, Cu+1.11+ is bonded to four S2- atoms to form a mixture of edge and corner-sharing CuS4 tetrahedra. There are a spread of Cu–S bond distances ranging from 2.36–2.42 Å. In the fifth Cu+1.11+ site, Cu+1.11+ is bonded to four S2- atoms to form a mixture of edge and corner-sharing CuS4 tetrahedra. There are two shorter (2.37 Å) and two longer (2.43 Å) Cu–S bond lengths. In the sixth Cu+1.11+ site, Cu+1.11+ is bonded to four S2- atoms to form a mixture of edge and corner-sharing CuS4 tetrahedra. There are a spread of Cu–S bond distances ranging from 2.35–2.41 Å. In the seventh Cu+1.11+ site, Cu+1.11+ is bonded to four S2- atoms to form a mixture of edge and corner-sharing CuS4 tetrahedra. There are a spread of Cu–S bond distances ranging from 2.37–2.40 Å. In the eighth Cu+1.11+ site, Cu+1.11+ is bonded to four S2- atoms to form a mixture of edge and corner-sharing CuS4 tetrahedra. There are a spread of Cu–S bond distances ranging from 2.34–2.40 Å. In the ninth Cu+1.11+ site, Cu+1.11+ is bonded to four S2- atoms to form a mixture of edge and corner-sharing CuS4 tetrahedra. There are two shorter (2.36 Å) and two longer (2.40 Å) Cu–S bond lengths. There are five inequivalent S2- sites. In the first S2- site, S2- is bonded in a body-centered cubic geometry to eight Cu+1.11+ atoms. In the second S2- site, S2- is bonded in a 7-coordinate geometry to seven Cu+1.11+ atoms. In the third S2- site, S2- is bonded in a 7-coordinate geometry to seven Cu+1.11+ atoms. In the fourth S2- site, S2- is bonded in a 7-coordinate geometry to seven Cu+1.11+ atoms. In the fifth S2- site, S2- is bonded in a 7-coordinate geometry to seven Cu+1.11+ atoms.
