Li2TiGeO5 crystallizes in the tetragonal P4/nmm space group. Li(1) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms. Ti(1) is bonded in a 5-coordinate geometry to one O(2) and four equivalent O(1) atoms. Ge(1) is bonded in a tetrahedral geometry to four equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Li(1), one Ti(1), and one Ge(1) atom to form a mixture of distorted edge and corner-sharing OLi2TiGe tetrahedra. In the second O site, O(2) is bonded in a distorted single-bond geometry to four equivalent Li(1) and one Ti(1) atom.
