MgVO3 crystallizes in the orthorhombic Cmmm space group. Mg(1) is bonded in a 5-coordinate geometry to one O(3) and four equivalent O(1) atoms. V(1) is bonded in a 5-coordinate geometry to one O(2) and four equivalent O(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Mg(1) and two equivalent V(1) atoms to form a mixture of distorted corner and edge-sharing OMg2V2 trigonal pyramids. In the second O site, O(2) is bonded in a linear geometry to two equivalent V(1) atoms. In the third O site, O(3) is bonded in a linear geometry to two equivalent Mg(1) atoms.
