Cu3VTe4 is Sulvanite structured and crystallizes in the cubic P-43m space group. V(1) is bonded to six equivalent Cu(1) and four equivalent Te(1) atoms to form distorted VCu6Te4 tetrahedra that share corners with six equivalent V(1)Cu6Te4 tetrahedra, corners with twelve equivalent Te(1)VCu3 tetrahedra, and faces with four equivalent Te(1)VCu3 tetrahedra. Cu(1) is bonded in a 6-coordinate geometry to two equivalent V(1) and four equivalent Te(1) atoms. Te(1) is bonded to one V(1) and three equivalent Cu(1) atoms to form TeVCu3 tetrahedra that share corners with three equivalent V(1)Cu6Te4 tetrahedra, corners with six equivalent Te(1)VCu3 tetrahedra, edges with three equivalent Te(1)VCu3 tetrahedra, and  a faceface with one V(1)Cu6Te4 tetrahedra.
