RbV(CuS2)2 crystallizes in the orthorhombic Ama2 space group. Rb(1) is bonded in a 9-coordinate geometry to one S(2), four equivalent S(1), and four equivalent S(3) atoms. V(1) is bonded to one S(2), one S(3), and two equivalent S(1) atoms to form VS4 tetrahedra that share edges with two equivalent Cu(1)S4 tetrahedra and edges with two equivalent Cu(2)S4 tetrahedra. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded to two equivalent S(1) and two equivalent S(2) atoms to form distorted CuS4 tetrahedra that share corners with two equivalent Cu(1)S4 tetrahedra, corners with four equivalent Cu(2)S4 tetrahedra, and edges with two equivalent V(1)S4 tetrahedra. In the second Cu site, Cu(2) is bonded to one S(2), one S(3), and two equivalent S(1) atoms to form distorted CuS4 tetrahedra that share corners with four equivalent Cu(1)S4 tetrahedra and edges with two equivalent V(1)S4 tetrahedra. There are three inequivalent S sites. In the first S site, S(1) is bonded in a 5-coordinate geometry to two equivalent Rb(1), one V(1), one Cu(1), and one Cu(2) atom. In the second S site, S(2) is bonded in a 5-coordinate geometry to one Rb(1), one V(1), one Cu(2), and two equivalent Cu(1) atoms. In the third S site, S(3) is bonded in a 6-coordinate geometry to four equivalent Rb(1), one V(1), and one Cu(2) atom.
