MgV4O8 crystallizes in the monoclinic Pm space group. Mg(1) is bonded in a see-saw-like geometry to two equivalent O(2) and two equivalent O(4) atoms. There are two inequivalent V sites. In the first V site, V(1) is bonded to one O(2), one O(3), two equivalent O(1), and two equivalent O(5) atoms to form a mixture of corner and edge-sharing VO6 octahedra. The corner-sharing octahedral tilt angles range from 6-39°. In the second V site, V(2) is bonded to one O(1), one O(4), two equivalent O(2), and two equivalent O(5) atoms to form a mixture of corner and edge-sharing VO6 octahedra. The corner-sharing octahedral tilt angles are 6°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a trigonal non-coplanar geometry to one V(2) and two equivalent V(1) atoms. 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 bent 150 degrees geometry to two equivalent V(1) atoms. In the fourth O site, O(4) is bonded in a see-saw-like geometry to two equivalent Mg(1) and two equivalent V(2) atoms. In the fifth O site, O(5) is bonded in a square co-planar geometry to two equivalent V(1) and two equivalent V(2) atoms.
