Li3GeO4 is Enargite structured and crystallizes in the orthorhombic Pmn2_1 space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form LiO4 tetrahedra that share corners with four equivalent Li(1)O4 tetrahedra, corners with four equivalent Li(2)O4 tetrahedra, and corners with four equivalent Ge(1)O4 tetrahedra. In the second Li site, Li(2) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form LiO4 tetrahedra that share corners with four equivalent Ge(1)O4 tetrahedra and corners with eight equivalent Li(1)O4 tetrahedra. Ge(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form GeO4 tetrahedra that share corners with four equivalent Li(2)O4 tetrahedra and corners with eight equivalent Li(1)O4 tetrahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded to one Li(2), two equivalent Li(1), and one Ge(1) atom to form corner-sharing OLi3Ge tetrahedra. In the second O site, O(2) is bonded to one Li(2), two equivalent Li(1), and one Ge(1) atom to form corner-sharing OLi3Ge tetrahedra. In the third O site, O(3) is bonded to one Li(2), two equivalent Li(1), and one Ge(1) atom to form corner-sharing OLi3Ge tetrahedra.
