Ge2BiO6 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to one O(4), one O(5), and two equivalent O(2) atoms to form GeO4 tetrahedra that share corners with three equivalent Bi(1)O6 pentagonal pyramids and corners with two equivalent Ge(1)O4 tetrahedra. In the second Ge site, Ge(2) is bonded to one O(3), one O(6), and two equivalent O(1) atoms to form GeO4 tetrahedra that share corners with three equivalent Bi(1)O6 pentagonal pyramids and corners with two equivalent Ge(2)O4 tetrahedra. Bi(1) is bonded to one O(3), one O(4), two equivalent O(5), and two equivalent O(6) atoms to form distorted BiO6 pentagonal pyramids that share corners with three equivalent Ge(1)O4 tetrahedra, corners with three equivalent Ge(2)O4 tetrahedra, and edges with two equivalent Bi(1)O6 pentagonal pyramids. There are six inequivalent O sites. In the first O site, O(6) is bonded in a distorted trigonal planar geometry to one Ge(2) and two equivalent Bi(1) atoms. In the second O site, O(1) is bonded in a distorted bent 120 degrees geometry to two equivalent Ge(2) atoms. In the third O site, O(2) is bonded in a bent 120 degrees geometry to two equivalent Ge(1) atoms. In the fourth O site, O(3) is bonded in a distorted bent 150 degrees geometry to one Ge(2) and one Bi(1) atom. In the fifth O site, O(4) is bonded in a bent 120 degrees geometry to one Ge(1) and one Bi(1) atom. In the sixth O site, O(5) is bonded in a distorted trigonal planar geometry to one Ge(1) and two equivalent Bi(1) atoms.
