MgCo(WO4)2 crystallizes in the triclinic P1 space group. Mg(1) is bonded in a 6-coordinate geometry to one O(1), one O(3), one O(4), one O(6), one O(7), and one O(8) atom. There are two inequivalent W sites. In the first W site, W(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form WO6 octahedra that share corners with four equivalent Co(1)O6 octahedra and edges with two equivalent W(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 32-55°.
