MgV4ZnO10 crystallizes in the monoclinic Pm space group. Mg(1) is bonded in a 5-coordinate geometry to one O(2) and four equivalent O(5) atoms. There are two inequivalent V sites. In the first V site, V(1) is bonded to one O(2), one O(4), one O(5), and two equivalent O(3) atoms to form a mixture of distorted corner and edge-sharing VO5 trigonal bipyramids. In the second V site, V(2) is bonded to one O(1), one O(3), one O(6), and two equivalent O(4) atoms to form a mixture of distorted corner and edge-sharing VO5 trigonal bipyramids. Zn(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(4), and two equivalent O(6) atoms. There are six inequivalent O sites. In the first O site, O(1) is bonded to two equivalent V(2) and two equivalent Zn(1) atoms to form corner-sharing OV2Zn2 tetrahedra. In the second O site, O(2) is bonded in a trigonal planar geometry to one Mg(1) and two equivalent V(1) atoms. In the third O site, O(3) is bonded in a trigonal non-coplanar geometry to one V(2) and two equivalent V(1) atoms. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to one V(1), two equivalent V(2), and one Zn(1) atom. In the fifth O site, O(5) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Mg(1) and one V(1) atom. In the sixth O site, O(6) is bonded in a bent 150 degrees geometry to one V(2) and one Zn(1) atom.
