The compound described by MgCo(WO4)2 crystallizes in the triclinic P-1 space group. Mg(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form MgO6 octahedra that share edges with two equivalent Co(1)O6 octahedra. W(1) is bonded in a 5-coordinate geometry to one O(2), one O(3), one O(4), and two equivalent O(1) atoms. Co(1) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms to form CoO6 octahedra that share edges with two equivalent Mg(1)O6 octahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to one Mg(1) and two equivalent W(1) atoms. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Mg(1), one W(1), and one Co(1) atom. In the third O site, O(3) is bonded in a T-shaped geometry to one Mg(1), one W(1), and one Co(1) atom. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to one W(1) and one Co(1) atom. is represented by the CIF card [CIF]
