The compound described by CeRh2O5 crystallizes in the orthorhombic Pnma space group. Ce(1) is bonded in a 7-coordinate geometry to one O(3), two equivalent O(1), and four equivalent O(2) atoms. Rh(1) is bonded to one O(3), two equivalent O(2), and three equivalent O(1) atoms to form a mixture of corner and edge-sharing RhO6 octahedra. The corner-sharing octahedral tilt angles range from 51-55°. There are three inequivalent O sites. In the first O site, O(1) is bonded to one Ce(1) and three equivalent Rh(1) atoms to form a mixture of distorted corner and edge-sharing OCeRh3 trigonal pyramids. In the second O site, O(2) is bonded in a distorted see-saw-like geometry to two equivalent Ce(1) and two equivalent Rh(1) atoms. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Ce(1) and two equivalent Rh(1) atoms. is represented by the CIF card [CIF]
