MgVPbO3 crystallizes in the tetragonal P4mm space group. Mg(1) is bonded in a 5-coordinate geometry to one O(1) and four equivalent O(2) atoms. V(1) is bonded in a distorted single-bond geometry to one O(1) and four equivalent O(2) atoms. Pb(1) is bonded in a 4-coordinate geometry to four equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to one Mg(1) and one V(1) atom. In the second O site, O(2) is bonded in a 6-coordinate geometry to two equivalent Mg(1), two equivalent V(1), and two equivalent Pb(1) atoms.
