The crystal structure described by Pb2Ge(SeO3)4 crystallizes in the monoclinic P2_1/c space group. Pb(1) is bonded in a 4-coordinate geometry to one O(3), one O(4), and two equivalent O(5) atoms. Ge(1) is bonded in an octahedral geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(6) atoms. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded in a distorted trigonal non-coplanar geometry to one O(1), one O(2), and one O(3) atom. In the second Se site, Se(2) is bonded in a distorted trigonal non-coplanar geometry to one O(4), one O(5), and one O(6) atom. There are six inequivalent O sites. In the first O site, O(6) is bonded in a bent 120 degrees geometry to one Ge(1) and one Se(2) atom. In the second O site, O(1) is bonded in a bent 120 degrees geometry to one Ge(1) and one Se(1) atom. In the third O site, O(2) is bonded in a bent 120 degrees geometry to one Ge(1) and one Se(1) atom. In the fourth O site, O(3) is bonded in a distorted single-bond geometry to one Pb(1) and one Se(1) atom. In the fifth O site, O(4) is bonded in a bent 120 degrees geometry to one Pb(1) and one Se(2) atom. In the sixth O site, O(5) is bonded in a distorted trigonal planar geometry to two equivalent Pb(1) and one Se(2) atom. is represented by the CIF card [CIF]
