The compound described by U(RhO3)2 is Hydrophilite-derived structured and crystallizes in the tetragonal P4_2/mnm space group. U(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form UO6 octahedra that share corners with eight equivalent Rh(1)O6 octahedra and edges with two equivalent Rh(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 49-52°. Rh(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form RhO6 octahedra that share corners with four equivalent U(1)O6 octahedra, corners with four equivalent Rh(1)O6 octahedra,  an edgeedge with one U(1)O6 octahedra, and  an edgeedge with one Rh(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 49-52°. There are two inequivalent O sites. In the first O site, O(2) is bonded in a trigonal planar geometry to one U(1) and two equivalent Rh(1) atoms. In the second O site, O(1) is bonded in a distorted trigonal planar geometry to one U(1) and two equivalent Rh(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
