The material structure described by Pb2MoO5 crystallizes in the monoclinic C2/m space group. Mo(1) is bonded in a tetrahedral geometry to one O(2), one O(4), and two equivalent O(3) atoms. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a distorted pentagonal planar geometry to one O(2), two equivalent O(1), and two equivalent O(3) atoms. In the second Pb site, Pb(2) is bonded in a 3-coordinate geometry to one O(4) and two equivalent O(1) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Pb(1) and two equivalent Pb(2) atoms to form edge-sharing OPb4 tetrahedra. In the second O site, O(2) is bonded in a distorted linear geometry to one Mo(1) and one Pb(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to one Mo(1) and one Pb(1) atom. In the fourth O site, O(4) is bonded in a distorted bent 120 degrees geometry to one Mo(1) and one Pb(2) atom. is represented by the CIF file [CIF]
