Ca2WAgO6 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 Ag(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 34-42°. Ag(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form AgO6 octahedra that share corners with six equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 34-42°. 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 Ag(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 Ag(1) atom. In the third O site, O(3) is bonded to two equivalent Ca(1), one W(1), and one Ag(1) atom to form distorted corner-sharing OCa2AgW tetrahedra.
