The structure described by Mg2WBiO6 crystallizes in the monoclinic P2_1/c space group. Mg(1) is bonded in a 4-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 Bi(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 47-56°. Bi(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form BiO6 octahedra that share corners with six equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 47-56°. 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 Bi(1) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Mg(1), one W(1), and one Bi(1) atom. In the third O site, O(3) is bonded to two equivalent Mg(1), one W(1), and one Bi(1) atom to form distorted corner-sharing OMg2BiW tetrahedra. is represented by the CIF file [CIF]
