The compound described by MgCo(WO4)2 crystallizes in the triclinic P1 space group. Mg(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 distorted MgO6 octahedra that share corners with two equivalent W(1)O6 octahedra, corners with two equivalent Co(1)O4 tetrahedra, edges with two equivalent W(1)O6 octahedra, and edges with two equivalent W(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 29-30°. 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 distorted WO6 octahedra that share corners with two equivalent Mg(1)O6 octahedra, corners with two equivalent Co(1)O4 tetrahedra, edges with two equivalent Mg(1)O6 octahedra, and edges with two equivalent W(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 29-30°. In the second W site, W(2) is bonded to one O(1), one O(2), one O(5), one O(6), one O(7), and one O(8) atom to form distorted WO6 octahedra that share corners with three equivalent Co(1)O4 tetrahedra, edges with two equivalent Mg(1)O6 octahedra, and edges with two equivalent W(1)O6 octahedra. Co(1) is bonded to one O(2), one O(3), one O(7), and one O(8) atom to form CoO4 tetrahedra that share corners with two equivalent Mg(1)O6 octahedra, corners with two equivalent W(1)O6 octahedra, and corners with three equivalent W(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 38-68°. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Mg(1), one W(1), and one W(2) atom. In the second O site, O(2) is bonded in a distorted tetrahedral geometry to one Mg(1), one W(1), one W(2), and one Co(1) atom. In the third O site, O(3) is bonded in a trigonal planar geometry to one Mg(1), one W(1), and one Co(1) atom. In the fourth O site, O(4) is bonded in a water-like geometry to one Mg(1) and one W(1) atom. In the fifth O site, O(5) is bonded in a distorted trigonal non-coplanar geometry to one Mg(1), one W(1), and one W(2) atom. In the sixth O site, O(6) is bonded in a 3-coordinate geometry to one Mg(1), one W(1), and one W(2) atom. In the seventh O site, O(7) is bonded in a bent 120 degrees geometry to one W(2) and one Co(1) atom. In the eighth O site, O(8) is bonded in a bent 150 degrees geometry to one W(2) and one Co(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
