The structure described by Ca2MnWO6 is Ilmenite-derived structured and crystallizes in the triclinic P1 space group. There are two inequivalent Ca sites. In the first Ca site, Ca(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom. In the second Ca site, Ca(2) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom. W(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form WO6 octahedra that share corners with six equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 27-34°. Mn(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form MnO6 octahedra that share corners with six equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 27-34°. There are six inequivalent O sites. In the first O site, O(1) is bonded to one Ca(1), one Ca(2), one W(1), and one Mn(1) atom to form a mixture of distorted edge and corner-sharing OCa2MnW tetrahedra. In the second O site, O(2) is bonded to one Ca(1), one Ca(2), one W(1), and one Mn(1) atom to form a mixture of distorted edge and corner-sharing OCa2MnW tetrahedra. In the third O site, O(3) is bonded in a distorted see-saw-like geometry to one Ca(1), one Ca(2), one W(1), and one Mn(1) atom. In the fourth O site, O(4) is bonded to one Ca(1), one Ca(2), one W(1), and one Mn(1) atom to form a mixture of distorted edge and corner-sharing OCa2MnW tetrahedra. In the fifth O site, O(5) is bonded to one Ca(1), one Ca(2), one W(1), and one Mn(1) atom to form a mixture of distorted edge and corner-sharing OCa2MnW tetrahedra. In the sixth O site, O(6) is bonded to one Ca(1), one Ca(2), one W(1), and one Mn(1) atom to form a mixture of distorted edge and corner-sharing OCa2MnW tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
