VCuS4 crystallizes in the orthorhombic Imma space group. V(1) is bonded to two equivalent S(1) and four equivalent S(2) atoms to form VS6 octahedra that share corners with six equivalent Cu(1)S4 tetrahedra and edges with two equivalent V(1)S6 octahedra. Cu(1) is bonded to two equivalent S(1) and two equivalent S(2) atoms to form CuS4 tetrahedra that share corners with six equivalent V(1)S6 octahedra. The corner-sharing octahedral tilt angles range from 55-56°. There are two inequivalent S sites. In the first S site, S(1) is bonded in a bent 120 degrees geometry to one V(1) and one Cu(1) atom. In the second S site, S(2) is bonded in a distorted trigonal planar geometry to two equivalent V(1) and one Cu(1) atom.
