The crystal structure described by PbGeO3 crystallizes in the trigonal R-3 space group. Pb(1) is bonded to two equivalent O(3) and three equivalent O(2) atoms to form distorted PbO5 square pyramids that share corners with two equivalent Pb(1)O5 square pyramids, corners with five equivalent Ge(1)O4 tetrahedra, and edges with three equivalent Pb(1)O5 square pyramids. Ge(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form GeO4 tetrahedra that share corners with five equivalent Pb(1)O5 square pyramids and corners with two equivalent Ge(1)O4 tetrahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to two equivalent Ge(1) atoms. In the second O site, O(2) is bonded in a distorted single-bond geometry to three equivalent Pb(1) and one Ge(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to two equivalent Pb(1) and one Ge(1) atom. is represented by the CIF card [CIF]
