Ge2SbO6 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 Sb(1)O6 octahedra and corners with two equivalent Ge(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 47-60°. 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 Sb(1)O6 octahedra and corners with two equivalent Ge(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 39-64°. Sb(1) is bonded to one O(3), one O(4), two equivalent O(5), and two equivalent O(6) atoms to form distorted SbO6 octahedra that share corners with three equivalent Ge(1)O4 tetrahedra, corners with three equivalent Ge(2)O4 tetrahedra, and edges with two equivalent Sb(1)O6 octahedra. 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 Sb(1) atoms. In the second O site, O(1) is bonded in a bent 150 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 bent 150 degrees geometry to one Ge(2) and one Sb(1) atom. In the fifth O site, O(4) is bonded in a distorted bent 120 degrees geometry to one Ge(1) and one Sb(1) atom. In the sixth O site, O(5) is bonded in a distorted trigonal planar geometry to one Ge(1) and two equivalent Sb(1) atoms.
