The material described by Pb3(VO4)2 crystallizes in the monoclinic P2_1/c space group. V(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one O(4) atom. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a distorted pentagonal planar geometry to one O(1), one O(3), one O(4), and two equivalent O(2) atoms. In the second Pb site, Pb(2) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one V(1), one Pb(1), and one Pb(2) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one V(1), one Pb(2), and two equivalent Pb(1) atoms. In the third O site, O(3) is bonded in a distorted single-bond geometry to one V(1), one Pb(1), and one Pb(2) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one V(1), one Pb(1), and one Pb(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
