The structure described by MgWTe3O12 crystallizes in the monoclinic P2 space group. Mg(1) is bonded in a 6-coordinate geometry to two equivalent O(2), two equivalent O(3), and two equivalent O(6) atoms. W(1) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(5) atoms to form WO6 octahedra that share corners with two equivalent Te(1)O6 octahedra and edges with two equivalent Te(2)O6 octahedra. The corner-sharing octahedral tilt angles are 34°. There are three inequivalent Te sites. In the first Te site, Te(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms to form TeO6 octahedra that share corners with two equivalent W(1)O6 octahedra and edges with two equivalent Te(3)O6 octahedra. The corner-sharing octahedral tilt angles are 34°. In the second Te site, Te(2) is bonded to two equivalent O(3), two equivalent O(5), and two equivalent O(6) atoms to form distorted TeO6 octahedra that share corners with two equivalent Te(3)O6 octahedra and edges with two equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles are 54°. In the third Te site, Te(3) is bonded to two equivalent O(2), two equivalent O(4), and two equivalent O(6) atoms to form a mixture of corner and edge-sharing TeO6 octahedra. The corner-sharing octahedral tilt angles are 54°. There are six inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one W(1) and one Te(1) atom. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to one Mg(1), one Te(1), and one Te(3) 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 Te(2) atom. In the fourth O site, O(4) is bonded in a water-like geometry to one Te(1) and one Te(3) atom. In the fifth O site, O(5) is bonded in a water-like geometry to one W(1) and one Te(2) atom. In the sixth O site, O(6) is bonded in a trigonal planar geometry to one Mg(1), one Te(2), and one Te(3) atom. is represented by the CIF card [CIF]
