LiVGeO5 crystallizes in the orthorhombic Cmme space group. Li(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form distorted LiO6 octahedra that share corners with two equivalent Li(1)O6 octahedra, corners with four equivalent Ge(1)O4 tetrahedra, corners with two equivalent V(1)O5 trigonal bipyramids, and edges with two equivalent V(1)O5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 56°. V(1) is bonded to one O(2) and four equivalent O(1) atoms to form distorted VO5 trigonal bipyramids that share corners with two equivalent Li(1)O6 octahedra, corners with four equivalent Ge(1)O4 tetrahedra, and edges with two equivalent Li(1)O6 octahedra. The corner-sharing octahedral tilt angles are 62°. Ge(1) is bonded to four equivalent O(1) atoms to form GeO4 tetrahedra that share corners with four equivalent Li(1)O6 octahedra and corners with four equivalent V(1)O5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 61°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Li(1), one V(1), and one Ge(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Li(1) and one V(1) atom.
