The structure described by Li2GeO3 is Enargite-like structured and crystallizes in the orthorhombic Cmc2_1 space group. Li(1) is bonded to one O(1) and three equivalent O(2) atoms to form LiO4 tetrahedra that share corners with five equivalent Ge(1)O4 tetrahedra and corners with seven equivalent Li(1)O4 tetrahedra. Ge(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form GeO4 tetrahedra that share corners with two equivalent Ge(1)O4 tetrahedra and corners with ten equivalent Li(1)O4 tetrahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Li(1) and two equivalent Ge(1) atoms to form OLi2Ge2 tetrahedra that share corners with two equivalent O(1)Li2Ge2 tetrahedra and corners with ten equivalent O(2)Li3Ge tetrahedra. In the second O site, O(2) is bonded to three equivalent Li(1) and one Ge(1) atom to form OLi3Ge tetrahedra that share corners with five equivalent O(1)Li2Ge2 tetrahedra and corners with seven equivalent O(2)Li3Ge tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
