Materials Data on Cu3SbS4 by Materials Project

Abstract

Cu3SbS4 is Enargite-like structured and crystallizes in the tetragonal I-42m space group. The structure is three-dimensional. there are two inequivalent Cu1+ sites. In the first Cu1+ site, Cu1+ is bonded to four equivalent S2- atoms to form CuS4 tetrahedra that share corners with four equivalent SbS4 tetrahedra and corners with eight CuS4 tetrahedra. All Cu–S bond lengths are 2.30 Å. In the second Cu1+ site, Cu1+ is bonded to four equivalent S2- atoms to form CuS4 tetrahedra that share corners with four equivalent SbS4 tetrahedra and corners with eight equivalent CuS4 tetrahedra. All Cu–S bond lengths are 2.31 Å. Sb5+ is bonded to four equivalent S2- atoms to form SbS4 tetrahedra that share corners with twelve CuS4 tetrahedra. All Sb–S bond lengths are 2.47 Å. S2- is bonded to three Cu1+ and one Sb5+ atom to form corner-sharing SCu3Sb tetrahedra.
