RbVCu3Se4 crystallizes in the cubic P-43m space group. Rb(1) is bonded to four equivalent Se(1) atoms to form RbSe4 tetrahedra that share corners with four equivalent V(1)Se4 tetrahedra and corners with twelve equivalent Cu(1)Se4 tetrahedra. V(1) is bonded to four equivalent Se(1) atoms to form VSe4 tetrahedra that share corners with four equivalent Rb(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 Rb(1)Se4 tetrahedra, corners with eight equivalent Cu(1)Se4 tetrahedra, and edges with two equivalent V(1)Se4 tetrahedra. Se(1) is bonded to one Rb(1), one V(1), and three equivalent Cu(1) atoms to form a mixture of distorted corner and edge-sharing SeRbVCu3 trigonal bipyramids.
