Materials Data on VCu3S4 by Materials Project
Cu3VS4 is Sulvanite structured and crystallizes in the cubic P-43m space group. The structure is three-dimensional. V5+ is bonded to four equivalent S2- atoms to form VS4 tetrahedra that share edges with six equivalent CuS4 tetrahedra. All V–S bond lengths are 2.21 Å. Cu1+ is bonded to four equivalent S2- atoms to form CuS4 tetrahedra that share corners with eight equivalent CuS4 tetrahedra and edges with two equivalent VS4 tetrahedra. All Cu–S bond lengths are 2.30 Å. S2- is bonded to one V5+ and three equivalent Cu1+ atoms to form a mixture of distorted corner and edge-sharing SVCu3 tetrahedra.
