The compound described by MgCd2(WO4)2 is beta indium sulfide-derived structured and crystallizes in the monoclinic P2 space group. Mg(1) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms to form distorted MgO6 octahedra that share corners with four equivalent W(1)O6 octahedra, edges with two equivalent Cd(1)O6 octahedra, edges with two equivalent Cd(2)O6 octahedra, and faces with two equivalent W(2)O6 octahedra.

In the second Cd site, Cd(2) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms to form distorted CdO6 octahedra that share corners with four equivalent W(1)O6 octahedra, corners with four equivalent W(2)O6 octahedra, edges with two equivalent Mg(1)O6 octahedra, and edges with two equivalent Cd(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 40-59°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one W(1), one Cd(1), and one Cd(2) atom. In the second O site, O(2) is bonded in a rectangular see-saw-like geometry to one Mg(1), one W(2), one Cd(1), and one Cd(2) 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 distorted corner-sharing OMgCdW2 trigonal pyramids.
