Sumario:The crystal structure of the title compound, dilithium germanium trimolybdenum octa­oxide, consists of distorted hexa­gonal-close-packed oxygen layers with stacking sequence ABAC along [001] that are held together by alternating lithium–germanium and molybdenum layers. The two Li(+) and Ge(4+) ions all have site symmetry 3m. and occupy, respectively, tetra­hedral and octa­hedral sites in the ratio 2:1. The Mo atom has a formal oxidation state of +3.3 and occupies an octa­hedral site (site symmetry .m.) and forms strongly bonded triangular cluster units [Mo—Mo distance = 2.4728 (8) Å] involving three MoO(6) octa­hedra that are each shared along two edges, constituting an Mo(3)O(13) unit.
