MgTiPbO3 crystallizes in the orthorhombic Pmm2 space group. Mg(1) is bonded in a distorted T-shaped geometry to two equivalent Pb(1), one O(3), and two equivalent O(1) atoms. Ti(1) is bonded to one O(1), two equivalent O(2), and two equivalent O(3) atoms to form corner-sharing TiO5 trigonal bipyramids. Pb(1) is bonded in a 4-coordinate geometry to two equivalent Mg(1) and two equivalent O(2) 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 Ti(1) atom. In the second O site, O(2) is bonded to two equivalent Ti(1) and two equivalent Pb(1) atoms to form distorted corner-sharing OTi2Pb2 tetrahedra. In the third O site, O(3) is bonded in a T-shaped geometry to one Mg(1) and two equivalent Ti(1) atoms.
