Cu3VO4 is Enargite-like structured and crystallizes in the tetragonal I-42m space group. V(1) is bonded to four equivalent O(1) atoms to form VO4 tetrahedra that share corners with four equivalent Cu(2)O4 tetrahedra and corners with eight equivalent Cu(1)O4 tetrahedra. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded to four equivalent O(1) atoms to form CuO4 tetrahedra that share corners with four equivalent V(1)O4 tetrahedra, corners with four equivalent Cu(1)O4 tetrahedra, and corners with four equivalent Cu(2)O4 tetrahedra. In the second Cu site, Cu(2) is bonded to four equivalent O(1) atoms to form CuO4 tetrahedra that share corners with four equivalent V(1)O4 tetrahedra and corners with eight equivalent Cu(1)O4 tetrahedra. O(1) is bonded to one V(1), one Cu(2), and two equivalent Cu(1) atoms to form corner-sharing OVCu3 tetrahedra.
