The material structure described by Li2FeGeO4 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 Fe(1)O4 tetrahedra, and corners with four equivalent Ge(1)O4 tetrahedra. Fe(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form FeO4 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 Fe(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 Fe(1), and one Ge(1) atom to form corner-sharing OLi2FeGe tetrahedra. In the second O site, O(2) is bonded to two equivalent Li(1), one Fe(1), and one Ge(1) atom to form corner-sharing OLi2FeGe tetrahedra. In the third O site, O(3) is bonded to two equivalent Li(1), one Fe(1), and one Ge(1) atom to form corner-sharing OLi2FeGe tetrahedra. is represented by the CIF file [CIF]
