The crystal structure described by Li2VGeO5 crystallizes in the tetragonal P4/nmm space group. Li(1) is bonded in a 6-coordinate geometry to two equivalent O(1) and four equivalent O(2) atoms. V(1) is bonded in a 5-coordinate geometry to one O(1) and four equivalent O(2) atoms. Ge(1) is bonded in a tetrahedral geometry to four equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to four equivalent Li(1) and one V(1) atom. In the second O site, O(2) is bonded to two equivalent Li(1), one V(1), and one Ge(1) atom to form a mixture of distorted corner and edge-sharing OLi2VGe tetrahedra. is represented by the CIF card [CIF]
