Materials Data on Cu9S5 by Materials Project

Abstract

Cu9S5 crystallizes in the triclinic P1 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 in a 3-coordinate geometry to four S2- atoms. There are a spread of Cu–S bond distances ranging from 2.30–2.77 Å. In the second Cu+1.11+ site, Cu+1.11+ is bonded in a 4-coordinate geometry to five S2- atoms. There are a spread of Cu–S bond distances ranging from 2.38–2.91 Å. In the third Cu+1.11+ site, Cu+1.11+ is bonded in a tetrahedral geometry to four S2- atoms. There are one shorter (2.37 Å) and three longer (2.38 Å) Cu–S bond lengths. In the fourth Cu+1.11+ site, Cu+1.11+ is bonded in a 4-coordinate geometry to six S2- atoms. There are a spread of Cu–S bond distances ranging from 2.46–3.14 Å. In the fifth Cu+1.11+ site, Cu+1.11+ is bonded in a distorted trigonal planar geometry to four S2- atoms. There are a spread of Cu–S bond distances ranging from 2.28–2.85 Å. In the sixth Cu+1.11+ site, Cu+1.11+ is bonded in a 4-coordinate geometry to five S2- atoms. There are a spread of Cu–S bond distances ranging from 2.38–3.15 Å. In the seventh Cu+1.11+ site, Cu+1.11+ is bonded in a 4-coordinate geometry to four S2- atoms. There are a spread of Cu–S bond distances ranging from 2.29–2.75 Å. In the eighth Cu+1.11+ site, Cu+1.11+ is bonded in a 4-coordinate geometry to six S2- atoms. There are a spread of Cu–S bond distances ranging from 2.41–3.10 Å. In the ninth Cu+1.11+ site, Cu+1.11+ is bonded in a distorted trigonal planar geometry to three S2- atoms. There are a spread of Cu–S bond distances ranging from 2.30–2.34 Å. There are five inequivalent S2- sites. In the first S2- site, S2- is bonded in a 9-coordinate geometry to six Cu+1.11+ atoms. In the second S2- site, S2- is bonded in a 9-coordinate geometry to nine Cu+1.11+ atoms. In the third S2- site, S2- is bonded in a 9-coordinate geometry to nine Cu+1.11+ atoms. In the fourth S2- site, S2- is bonded in a 9-coordinate geometry to nine Cu+1.11+ atoms. In the fifth S2- site, S2- is bonded in a distorted hexagonal bipyramidal geometry to eight Cu+1.11+ atoms.
