The compound described by Mg2WSbO6 crystallizes in the monoclinic P2_1/c space group. Mg(1) is bonded in a 5-coordinate geometry to one O(1), two equivalent O(2), and two equivalent O(3) atoms. W(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form WO6 octahedra that share corners with six equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 43-55°. Sb(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form SbO6 octahedra that share corners with six equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 43-55°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Mg(1), one W(1), and one Sb(1) atom. In the second O site, O(2) is bonded to two equivalent Mg(1), one W(1), and one Sb(1) atom to form a mixture of distorted corner and edge-sharing OMg2SbW tetrahedra. In the third O site, O(3) is bonded in a 4-coordinate geometry to two equivalent Mg(1), one W(1), and one Sb(1) atom. is represented by the CIF file [CIF]
