The structure described by Li2MnGeO4 is Stannite-like structured and crystallizes in the orthorhombic Pmn2_1 space group. Li(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form LiO4 tetrahedra that share corners with four equivalent Li(1)O4 tetrahedra, corners with four equivalent Mn(1)O4 tetrahedra, and corners with four equivalent Ge(1)O4 tetrahedra. Mn(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form MnO4 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(1), one O(2), and two equivalent O(3) atoms to form GeO4 tetrahedra that share corners with four equivalent Mn(1)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 two equivalent Li(1), one Mn(1), and one Ge(1) atom to form corner-sharing OLi2MnGe tetrahedra. In the second O site, O(2) is bonded to two equivalent Li(1), one Mn(1), and one Ge(1) atom to form corner-sharing OLi2MnGe tetrahedra. In the third O site, O(3) is bonded to two equivalent Li(1), one Mn(1), and one Ge(1) atom to form corner-sharing OLi2MnGe tetrahedra. is represented by the CIF card [CIF]
