LiVGeO5 crystallizes in the monoclinic P2_1/m space group. Li(1) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms to form distorted LiO6 octahedra that share corners with four equivalent Ge(1)O4 tetrahedra and edges with two equivalent Li(1)O6 octahedra. V(1) is bonded in a 5-coordinate geometry to one O(1), one O(2), one O(4), and two equivalent O(3) atoms. Ge(1) is bonded to one O(1), one O(4), and two equivalent O(3) atoms to form GeO4 tetrahedra that share corners with four equivalent Li(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 59-61°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to 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. In the third O site, O(3) is bonded in a trigonal planar geometry to one Li(1), one V(1), and one Ge(1) atom. In the fourth O site, O(4) is bonded to two equivalent Li(1), one V(1), and one Ge(1) atom to form distorted corner-sharing OLi2VGe tetrahedra.
