The material structure described by V(GeO3)2 crystallizes in the triclinic P-1 space group. V(1) is bonded to one O(3), one O(4), two equivalent O(5), and two equivalent O(6) 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(1), one O(2), one O(4), and one O(5) atom 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 31-62°. In the second Ge site, Ge(2) is bonded to one O(1), one O(2), one O(3), and one O(6) atom 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 33-60°. There are six inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Ge(1) and one Ge(2) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Ge(1) and one Ge(2) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one V(1) and one Ge(2) atom. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to one V(1) and one Ge(1) atom. In the fifth O site, O(5) is bonded in a trigonal planar geometry to two equivalent V(1) and one Ge(1) atom. In the sixth O site, O(6) is bonded in a trigonal planar geometry to two equivalent V(1) and one Ge(2) atom. is represented by the CIF card [CIF]
