Abstract

BaCu6(GeS4)2 is Chalcostibite-derived structured and crystallizes in the orthorhombic Pbcm space group. The structure is three-dimensional. Ba2+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are a spread of Ba–S bond distances ranging from 3.06–3.43 Å. There are three inequivalent Cu1+ sites. In the first Cu1+ site, Cu1+ is bonded to four S2- atoms to form CuS4 tetrahedra that share corners with four CuS4 tetrahedra and corners with four GeS4 tetrahedra. There are a spread of Cu–S bond distances ranging from 2.31–2.44 Å. In the second Cu1+ site, Cu1+ is bonded in a trigonal planar geometry to three S2- atoms. There are a spread of Cu–S bond distances ranging from 2.28–2.33 Å. In the third Cu1+ site, Cu1+ is bonded to four S2- atoms to form CuS4 tetrahedra that share corners with four CuS4 tetrahedra and corners with four GeS4 tetrahedra. There are a spread of Cu–S bond distances ranging from 2.28–2.37 Å. There are two inequivalent Ge4+ sites. In the first Ge4+ site, Ge4+ is bonded to four S2- atoms to form GeS4 tetrahedra that share corners with eight CuS4 tetrahedra. There are a spread of Ge–S bond distances ranging from 2.23–2.29 Å.
