The compound described by MgCd2(WO4)2 crystallizes in the monoclinic P2 space group. Mg(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form distorted MgO6 octahedra that share edges with two equivalent W(1)O6 octahedra and edges with two equivalent W(2)O6 octahedra. There are two inequivalent W sites. In the first W site, W(1) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms to form WO6 octahedra that share edges with two equivalent Mg(1)O6 octahedra and edges with two equivalent W(2)O6 octahedra. In the second W site, W(2) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms to form WO6 octahedra that share edges with two equivalent Mg(1)O6 octahedra and edges with two equivalent W(1)O6 octahedra. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 6-coordinate geometry to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. In the second Cd site, Cd(2) is bonded in a distorted linear geometry to two equivalent O(1) and two equivalent O(4) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Mg(1), one W(1), and one Cd(2) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Mg(1), one W(2), and one Cd(1) atom. In the third O site, O(3) is bonded to one Mg(1), one W(1), one W(2), and one Cd(1) atom to form a mixture of corner and edge-sharing OMgCdW2 trigonal pyramids. In the fourth O site, O(4) is bonded in a distorted water-like geometry to one W(1), one W(2), one Cd(1), and one Cd(2) atom. is represented by the CIF file [CIF]
