The crystal structure described by MgV2CdO6 crystallizes in the monoclinic Cm space group. Mg(1) is bonded to one O(2), one O(4), one O(5), and two equivalent O(6) atoms to form distorted MgO5 square pyramids that share corners with two equivalent Mg(1)O5 square pyramids,  a cornercorner with one V(2)O5 trigonal bipyramid, corners with two equivalent V(1)O5 trigonal bipyramids, and edges with two equivalent V(2)O5 trigonal bipyramids. There are two inequivalent V sites. In the first V site, V(1) is bonded to one O(1), one O(2), one O(4), and two equivalent O(3) atoms to form distorted VO5 trigonal bipyramids that share corners with two equivalent Mg(1)O5 square pyramids, corners with two equivalent V(1)O5 trigonal bipyramids, and edges with two equivalent V(2)O5 trigonal bipyramids. In the second V site, V(2) is bonded to one O(3), one O(5), one O(6), and two equivalent O(2) atoms to form distorted VO5 trigonal bipyramids that share  a cornercorner with one Mg(1)O5 square pyramid, corners with two equivalent V(2)O5 trigonal bipyramids, edges with two equivalent Mg(1)O5 square pyramids, and edges with two equivalent V(1)O5 trigonal bipyramids. Cd(1) is bonded in a 5-coordinate geometry to one O(1), one O(3), one O(6), and two equivalent O(4) atoms. There are six inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one V(1) and one Cd(1) atom. In the second O site, O(2) is bonded in a rectangular see-saw-like geometry to one Mg(1), one V(1), and two equivalent V(2) atoms. In the third O site, O(3) is bonded in a 4-coordinate geometry to one V(2), two equivalent V(1), and one Cd(1) atom. In the fourth O site, O(4) is bonded in a distorted see-saw-like geometry to one Mg(1), one V(1), and two equivalent Cd(1) atoms. In the fifth O site, O(5) is bonded in a bent 150 degrees geometry to one Mg(1) and one V(2) atom. In the sixth O site, O(6) is bonded in a 4-coordinate geometry to two equivalent Mg(1), one V(2), and one Cd(1) atom. is represented by the CIF file [CIF]
