MgVPbO3 crystallizes in the orthorhombic Pmm2 space group. Mg(1) is bonded in a distorted T-shaped geometry to two equivalent Pb(1), one O(2), and two equivalent O(1) atoms. V(1) is bonded to one O(1), two equivalent O(2), and two equivalent O(3) atoms to form corner-sharing VO5 trigonal bipyramids. Pb(1) is bonded in a 6-coordinate geometry to two equivalent Mg(1), two equivalent O(2), and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a T-shaped geometry to two equivalent Mg(1) and one V(1) atom. In the second O site, O(2) is bonded in a T-shaped geometry to one Mg(1), two equivalent V(1), and two equivalent Pb(1) atoms. In the third O site, O(3) is bonded to two equivalent V(1) and two equivalent Pb(1) atoms to form distorted corner-sharing OV2Pb2 tetrahedra.
