The crystal structure described by LiCu2(RhO2)4 crystallizes in the trigonal R-3m space group. Li(1) is bonded in a 8-coordinate geometry to two equivalent Cu(1) and six equivalent O(1) atoms. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form edge-sharing RhO6 octahedra. In the second Rh site, Rh(2) is bonded to six equivalent O(1) atoms to form edge-sharing RhO6 octahedra. Cu(1) is bonded in a 5-coordinate geometry to one Li(1), one O(2), and three equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Li(1), one Rh(2), two equivalent Rh(1), and one Cu(1) atom to form OLiCuRh3 square pyramids that share corners with six equivalent O(1)LiCuRh3 square pyramids, corners with three equivalent O(2)CuRh3 trigonal pyramids, edges with six equivalent O(1)LiCuRh3 square pyramids, and  an edgeedge with one O(2)CuRh3 trigonal pyramid. In the second O site, O(2) is bonded to three equivalent Rh(1) and one Cu(1) atom to form distorted OCuRh3 trigonal pyramids that share corners with nine equivalent O(1)LiCuRh3 square pyramids, corners with three equivalent O(2)CuRh3 trigonal pyramids, and edges with three equivalent O(1)LiCuRh3 square pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
