VCu3PbSe4 crystallizes in the cubic P-43m space group. V(1) is bonded to four equivalent Se(1) atoms to form VSe4 tetrahedra that share corners with four equivalent Pb(1)Se4 tetrahedra and edges with six equivalent Cu(1)Se4 tetrahedra. Cu(1) is bonded to four equivalent Se(1) atoms to form distorted CuSe4 tetrahedra that share corners with four equivalent Pb(1)Se4 tetrahedra, corners with eight equivalent Cu(1)Se4 tetrahedra, and edges with two equivalent V(1)Se4 tetrahedra. Pb(1) is bonded to four equivalent Se(1) atoms to form PbSe4 tetrahedra that share corners with four equivalent V(1)Se4 tetrahedra and corners with twelve equivalent Cu(1)Se4 tetrahedra. Se(1) is bonded in a 5-coordinate geometry to one V(1), three equivalent Cu(1), and one Pb(1) atom.
