Ca2VWO6 crystallizes in the triclinic P-1 space group. Ca(1) is bonded in a 5-coordinate geometry to one O(2), two equivalent O(1), and two equivalent O(3) atoms. V(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form VO6 octahedra that share corners with six equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 24-33°. 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 V(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 24-33°. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Ca(1), one V(1), and one W(1) atom to form a mixture of distorted corner and edge-sharing OCa2VW trigonal pyramids. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Ca(1), one V(1), and one W(1) atom. In the third O site, O(3) is bonded in a distorted see-saw-like geometry to two equivalent Ca(1), one V(1), and one W(1) atom.
