The compound described by Li2ZnGeO4 is Stannite-like structured and crystallizes in the monoclinic Pc space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form LiO4 tetrahedra that share corners with four equivalent Li(2)O4 tetrahedra, corners with four equivalent Zn(1)O4 tetrahedra, and corners with four equivalent Ge(1)O4 tetrahedra. In the second Li site, Li(2) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form LiO4 tetrahedra that share corners with four equivalent Li(1)O4 tetrahedra, corners with four equivalent Zn(1)O4 tetrahedra, and corners with four equivalent Ge(1)O4 tetrahedra. Zn(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form ZnO4 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. Ge(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form GeO4 tetrahedra that share corners with four equivalent Li(1)O4 tetrahedra, corners with four equivalent Li(2)O4 tetrahedra, and corners with four equivalent Zn(1)O4 tetrahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded to one Li(1), one Li(2), one Zn(1), and one Ge(1) atom to form corner-sharing OLi2ZnGe tetrahedra. In the second O site, O(2) is bonded to one Li(1), one Li(2), one Zn(1), and one Ge(1) atom to form corner-sharing OLi2ZnGe tetrahedra. In the third O site, O(3) is bonded to one Li(1), one Li(2), one Zn(1), and one Ge(1) atom to form corner-sharing OLi2ZnGe tetrahedra. In the fourth O site, O(4) is bonded to one Li(1), one Li(2), one Zn(1), and one Ge(1) atom to form corner-sharing OLi2ZnGe tetrahedra. is represented by the CIF file [CIF]
