The material described by Ca2WSbO6 crystallizes in the monoclinic P2_1/c space group. Ca(1) is bonded in a 8-coordinate geometry to two equivalent O(3), three equivalent O(1), and three equivalent O(2) 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 35-40°. 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 35-40°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to three equivalent Ca(1), one W(1), and one Sb(1) atom. In the second O site, O(2) is bonded in a 5-coordinate geometry to three equivalent Ca(1), one W(1), and one Sb(1) atom. In the third O site, O(3) is bonded in a distorted see-saw-like geometry to two equivalent Ca(1), one W(1), and one Sb(1) atom. is represented by the CIF file [CIF]
