The structure described by MgPb4(WO5)2 crystallizes in the monoclinic Cm space group. Mg(1) is bonded in a distorted trigonal non-coplanar geometry to one Pb(2), one O(2), and two equivalent O(4) atoms. There are two inequivalent W sites. In the first W site, W(1) is bonded in a tetrahedral geometry to one O(2), one O(6), and two equivalent O(5) atoms. In the second W site, W(2) is bonded in a tetrahedral geometry to one O(3), one O(7), and two equivalent O(4) atoms. There are four 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(5) atoms. In the second Pb site, Pb(2) is bonded in a 3-coordinate geometry to one Mg(1) and two equivalent O(1) atoms. In the third Pb site, Pb(3) is bonded in a distorted T-shaped geometry to one O(7) and two equivalent O(1) atoms. In the fourth Pb site, Pb(4) is bonded in a 3-coordinate geometry to one O(6) and two equivalent O(1) atoms. There are seven inequivalent O sites. In the first O site, O(1) is bonded to one Pb(1), one Pb(2), one Pb(3), and one Pb(4) atom to form edge-sharing OPb4 tetrahedra. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Mg(1) and one W(1) atom. In the third O site, O(3) is bonded in a single-bond geometry to one W(2) atom. In the fourth O site, O(4) is bonded in a linear geometry to one Mg(1) and one W(2) atom. In the fifth O site, O(5) is bonded in a bent 150 degrees geometry to one W(1) and one Pb(1) atom. In the sixth O site, O(6) is bonded in a distorted bent 150 degrees geometry to one W(1) and one Pb(4) atom. In the seventh O site, O(7) is bonded in a bent 150 degrees geometry to one W(2) and one Pb(3) atom. is represented by the Crystallographic Information File (CIF) [CIF]
