V(GeO3)2 crystallizes in the monoclinic P2_1/c space group. V(1) is bonded to one O(2), one O(6), two equivalent O(3), and two equivalent O(5) atoms to form distorted VO6 octahedra that share corners with three equivalent Ge(1)O4 tetrahedra, corners with three equivalent Ge(2)O4 tetrahedra, and edges with two equivalent V(1)O6 octahedra. There are two inequivalent Ge sites. In the first Ge site, 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 three equivalent V(1)O6 octahedra and corners with two equivalent Ge(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 45-58°. In the second Ge site, Ge(2) is bonded to one O(5), one O(6), and two equivalent O(4) atoms to form GeO4 tetrahedra that share corners with three equivalent V(1)O6 octahedra and corners with two equivalent Ge(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 28-61°. There are six 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 bent 150 degrees geometry to one V(1) and one Ge(1) atom. In the third O site, O(3) is bonded in a trigonal planar geometry to two equivalent V(1) and one Ge(1) atom. In the fourth O site, O(4) is bonded in a bent 120 degrees geometry to two equivalent Ge(2) atoms. In the fifth O site, O(5) is bonded in a trigonal planar geometry to two equivalent V(1) and one Ge(2) atom. In the sixth O site, O(6) is bonded in a bent 150 degrees geometry to one V(1) and one Ge(2) atom.
