The material described by V2GeO4F2 crystallizes in the orthorhombic Pnma space group. V(1) is bonded to one O(2), one O(3), two equivalent O(1), and two equivalent F(1) atoms to form VO4F2 octahedra that share corners with two equivalent V(1)O4F2 octahedra, corners with four equivalent Ge(1)O4 tetrahedra, and edges with two equivalent V(1)O4F2 octahedra. The corner-sharing octahedral tilt angles are 40°. 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 eight equivalent V(1)O4F2 octahedra. The corner-sharing octahedral tilt angles range from 50-54°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to two equivalent V(1) and one Ge(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent V(1) and one Ge(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to two equivalent V(1) and one Ge(1) atom. F(1) is bonded in a bent 150 degrees geometry to two equivalent V(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
