The material described by Pb2MgWO6 is Pb(Zr_(1-x)Ti_x)O3-derived structured and crystallizes in the orthorhombic Pnma space group. Mg(1) is bonded to one O(1), one O(2), one O(3), one O(4), and two equivalent O(5) atoms to form MgO6 octahedra that share corners with six equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 2-13°. W(1) is bonded to one O(1), one O(2), one O(3), one O(4), and two equivalent O(5) atoms to form WO6 octahedra that share corners with six equivalent Mg(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 2-13°. Pb(1) is bonded in a 4-coordinate geometry to one O(1), one O(2), and two equivalent O(5) atoms. There are five inequivalent O sites. In the first O site, O(5) is bonded in a distorted rectangular see-saw-like geometry to one Mg(1), one W(1), and two equivalent Pb(1) atoms. In the second O site, O(1) is bonded in a distorted see-saw-like geometry to one Mg(1), one W(1), and two equivalent Pb(1) atoms. In the third O site, O(2) is bonded in a distorted see-saw-like geometry to one Mg(1), one W(1), and two equivalent Pb(1) atoms. In the fourth O site, O(3) is bonded in a linear geometry to one Mg(1) and one W(1) atom. In the fifth O site, O(4) is bonded in a linear geometry to one Mg(1) and one W(1) atom. is represented by the CIF card [CIF]
