Materials Data on Cu5Si2S7 by Materials Project
Abstract
Cu5Si2S7 is Enargite-like structured and crystallizes in the monoclinic Cc space group. The structure is three-dimensional. there are five inequivalent Cu+1.20+ sites. In the first Cu+1.20+ site, Cu+1.20+ is bonded to four S2- atoms to form CuS4 tetrahedra that share corners with five SiS4 tetrahedra and corners with seven CuS4 tetrahedra. There are a spread of Cu–S bond distances ranging from 2.27–2.36 Å. In the second Cu+1.20+ site, Cu+1.20+ is bonded to four S2- atoms to form CuS4 tetrahedra that share corners with four SiS4 tetrahedra and corners with eight CuS4 tetrahedra. There are a spread of Cu–S bond distances ranging from 2.28–2.34 Å. In the third Cu+1.20+ site, Cu+1.20+ is bonded to four S2- atoms to form CuS4 tetrahedra that share corners with four SiS4 tetrahedra and corners with eight CuS4 tetrahedra. There are a spread of Cu–S bond distances ranging from 2.28–2.30 Å. In the fourth Cu+1.20+ site, Cu+1.20+ is bonded to four S2- atoms to form CuS4 tetrahedra that share corners with five SiS4 tetrahedra and corners with seven CuS4 tetrahedra. There are a spread of Cu–S bond distances ranging from 2.26–2.39 Å. In the fifth Cu+1.20+ site, Cu+1.20+ is bonded to four S2- atoms to formmore »
