The material structure described by 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°. 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 four equivalent Co(1)O6 octahedra and edges with two equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 35-53°. Co(1) is bonded to one O(2), one O(3), one O(4), one O(6), one O(7), and one O(8) atom to form CoO6 octahedra that share corners with four equivalent W(1)O6 octahedra and corners with four equivalent W(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 32-55°. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to one Mg(1), one W(1), and one W(2) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to one W(1), one W(2), and one Co(1) atom. In the third O site, O(3) is bonded in a distorted 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 distorted T-shaped geometry to one Mg(1), one W(1), and one Co(1) atom. In the fifth O site, O(5) is bonded in a water-like geometry to one W(1) and one W(2) atom. In the sixth O site, O(6) is bonded in a trigonal pyramidal geometry to one Mg(1), one W(1), one W(2), and one Co(1) atom. In the seventh O site, O(7) is bonded in a distorted trigonal planar geometry to one Mg(1), one W(2), and one Co(1) atom. In the eighth O site, O(8) is bonded in a T-shaped geometry to one Mg(1), one W(2), and one Co(1) atom. is represented by the CIF card [CIF]
