The crystal structure described by Pb3(VO4)2 crystallizes in the trigonal R-3m space group. V(1) is bonded in a tetrahedral geometry to one O(1) and three 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 one O(1) and three equivalent O(2) atoms. In the second Pb site, Pb(2) is bonded in a distorted hexagonal planar geometry to six equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to one V(1) and one Pb(1) atom. In the second O site, O(2) 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]
