The material described by Li2MgGeO4 is Stannite-like structured and crystallizes in the orthorhombic Pmn2_1 space group. Li(1) is bonded to one O(1), one O(3), and two equivalent O(2) atoms to form LiO4 tetrahedra that share corners with four equivalent Li(1)O4 tetrahedra, corners with four equivalent Mg(1)O4 tetrahedra, and corners with four equivalent Ge(1)O4 tetrahedra. Mg(1) is bonded to one O(1), one O(3), and two equivalent O(2) atoms to form MgO4 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(3), and two equivalent O(2) atoms to form GeO4 tetrahedra that share corners with four equivalent Mg(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 Mg(1), and one Ge(1) atom to form corner-sharing OLi2MgGe tetrahedra. In the second O site, O(2) is bonded to two equivalent Li(1), one Mg(1), and one Ge(1) atom to form corner-sharing OLi2MgGe tetrahedra. In the third O site, O(3) is bonded to two equivalent Li(1), one Mg(1), and one Ge(1) atom to form corner-sharing OLi2MgGe tetrahedra. is represented by the CIF card [CIF]
