LiRhGeO4 is Spinel-derived structured and crystallizes in the orthorhombic Imma space group. Li(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form LiO4 tetrahedra that share corners with six equivalent Rh(1)O6 octahedra and corners with six equivalent Ge(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 54-63°. Rh(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form RhO6 octahedra that share corners with six equivalent Li(1)O4 tetrahedra, edges with two equivalent Rh(1)O6 octahedra, and edges with four equivalent Ge(1)O6 octahedra. Ge(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form GeO6 octahedra that share corners with six equivalent Li(1)O4 tetrahedra, edges with two equivalent Ge(1)O6 octahedra, and edges with four equivalent Rh(1)O6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted rectangular see-saw-like geometry to one Li(1), one Rh(1), and two equivalent Ge(1) atoms. In the second O site, O(2) is bonded to one Li(1), two equivalent Rh(1), and one Ge(1) atom to form a mixture of distorted edge and corner-sharing OLiGeRh2 tetrahedra.
