The material described by Rb4MgV2(AgS4)2 crystallizes in the triclinic P-1 space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 5-coordinate geometry to one S(2), one S(3), one S(4), and two equivalent S(1) atoms. In the second Rb site, Rb(2) is bonded in a 6-coordinate geometry to one S(1), two equivalent S(4), and three equivalent S(3) atoms. Mg(1) is bonded in a square co-planar geometry to two equivalent S(1) and two equivalent S(2) atoms. V(1) is bonded to one S(1), one S(2), one S(3), and one S(4) atom to form VS4 tetrahedra that share edges with two equivalent Ag(1)S4 tetrahedra. Ag(1) is bonded to one S(1), one S(2), one S(3), and one S(4) atom to form distorted AgS4 tetrahedra that share edges with two equivalent V(1)S4 tetrahedra. There are four inequivalent S sites. In the first S site, S(1) is bonded in a 6-coordinate geometry to one Rb(2), two equivalent Rb(1), one Mg(1), one V(1), and one Ag(1) atom. In the second S site, S(2) is bonded in a 4-coordinate geometry to one Rb(1), one Mg(1), one V(1), and one Ag(1) atom. In the third S site, S(3) is bonded in a 6-coordinate geometry to one Rb(1), three equivalent Rb(2), one V(1), and one Ag(1) atom. In the fourth S site, S(4) is bonded in a 5-coordinate geometry to one Rb(1), two equivalent Rb(2), one V(1), and one Ag(1) atom. is represented by the CIF card [CIF]
