The compound described by V2Ge2O7 crystallizes in the monoclinic C2/c space group. V(1) is bonded to one O(2), two equivalent O(3), and two equivalent O(4) atoms to form VO5 trigonal bipyramids that share corners with five equivalent Ge(1)O4 tetrahedra and edges with two equivalent V(1)O5 trigonal bipyramids. Ge(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form GeO4 tetrahedra that share  a cornercorner with one Ge(1)O4 tetrahedra and corners with five equivalent V(1)O5 trigonal bipyramids. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 150 degrees geometry to two equivalent Ge(1) atoms. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one 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. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to two equivalent V(1) and one Ge(1) atom. is represented by the CIF file [CIF]
