The structure described by MgCu2(RhS2)4 crystallizes in the orthorhombic Imm2 space group. Mg(1) is bonded in a body-centered cubic geometry to two equivalent Rh(1), two equivalent Rh(2), two equivalent S(2), and two equivalent S(3) atoms. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 7-coordinate geometry to one Mg(1), one S(2), one S(4), two equivalent S(1), and two equivalent S(3) atoms. In the second Rh site, Rh(2) is bonded in a 7-coordinate geometry to one Mg(1), one S(1), one S(3), two equivalent S(2), and two equivalent S(4) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a tetrahedral geometry to two equivalent S(1) and two equivalent S(4) atoms. In the second Cu site, Cu(2) is bonded in a tetrahedral geometry to two equivalent S(2) and two equivalent S(3) atoms. There are four inequivalent S sites. In the first S site, S(1) is bonded in a distorted rectangular see-saw-like geometry to one Rh(2), two equivalent Rh(1), and one Cu(1) atom. In the second S site, S(2) is bonded in a distorted linear geometry to one Mg(1), one Rh(1), two equivalent Rh(2), and one Cu(2) atom. In the third S site, S(3) is bonded in a distorted linear geometry to one Mg(1), one Rh(2), two equivalent Rh(1), and one Cu(2) atom. In the fourth S site, S(4) is bonded in a distorted rectangular see-saw-like geometry to one Rh(1), two equivalent Rh(2), and one Cu(1) atom. is represented by the CIF file [CIF]
