The crystal structure described by Ca2WBiO6 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 Bi(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 36-43°. 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 36-43°. 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 Bi(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 Bi(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 Bi(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
