The material described by Pb3GeO5 crystallizes in the orthorhombic Cmm2 space group. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a distorted pentagonal planar geometry to one O(3), two equivalent O(1), and two equivalent O(2) atoms. In the second Pb site, Pb(2) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. Ge(1) is bonded in a tetrahedral geometry to two equivalent O(1) and two equivalent O(2) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Pb(1), two equivalent Pb(2), and one Ge(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one Pb(1), two equivalent Pb(2), and one Ge(1) atom. In the third O site, O(3) is bonded to one Pb(1) and four equivalent Pb(2) atoms to form corner-sharing OPb5 square pyramids. is represented by the CIF file [CIF]
