The material structure described by Li2NiGeO4 is Stannite-like structured and crystallizes in the orthorhombic Pnma space group. 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 two equivalent Li(1)O4 tetrahedra, corners with four equivalent Ni(1)O4 tetrahedra, corners with four equivalent Ge(1)O4 tetrahedra, and  an edgeedge with one Li(1)O4 tetrahedra. Ni(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form NiO4 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 Ni(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 Ni(1), and one Ge(1) atom to form a mixture of distorted edge and corner-sharing OLi2NiGe tetrahedra. In the second O site, O(2) is bonded to two equivalent Li(1), one Ni(1), and one Ge(1) atom to form corner-sharing OLi2NiGe tetrahedra. In the third O site, O(3) is bonded to two equivalent Li(1), one Ni(1), and one Ge(1) atom to form corner-sharing OLi2NiGe tetrahedra. is represented by the CIF file [CIF]
