The structure described by MgZrTi(PbO3)2 crystallizes in the monoclinic Pm space group. Mg(1) is bonded in a 4-coordinate geometry to one Pb(2), two equivalent O(1), and two equivalent O(2) atoms. Zr(1) is bonded in a 5-coordinate geometry to one O(4), two equivalent O(1), and two equivalent O(2) atoms. Ti(1) is bonded in a 5-coordinate geometry to one O(3), two equivalent O(1), and two equivalent O(2) atoms. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(2) atoms. In the second Pb site, Pb(2) is bonded in a 4-coordinate geometry to one Mg(1), one O(4), and two equivalent O(3) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded to one Mg(1), one Zr(1), one Ti(1), and one Pb(1) atom to form distorted edge-sharing OMgZrTiPb tetrahedra. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Mg(1), one Zr(1), one Ti(1), and one Pb(1) atom. In the third O site, O(3) is bonded in a single-bond geometry to one Ti(1) and two equivalent Pb(2) atoms. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one Zr(1) and one Pb(2) atom. is represented by the CIF file [CIF]
