The material described by Rh2Pt2O5 crystallizes in the tetragonal P4/mmm space group. Rh(1) is bonded in a 5-coordinate geometry to one O(2) and four equivalent O(1) atoms. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a body-centered cubic geometry to eight equivalent O(1) atoms. In the second Pt site, Pt(2) is bonded in a square co-planar geometry to four equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Rh(1) and two equivalent Pt(1) atoms to form OPt2Rh2 tetrahedra that share corners with two equivalent O(2)Pt4Rh2 octahedra, corners with ten equivalent O(1)Pt2Rh2 tetrahedra, and edges with five equivalent O(1)Pt2Rh2 tetrahedra. The corner-sharing octahedral tilt angles are 58°. In the second O site, O(2) is bonded to two equivalent Rh(1) and four equivalent Pt(2) atoms to form OPt4Rh2 octahedra that share corners with four equivalent O(2)Pt4Rh2 octahedra, corners with eight equivalent O(1)Pt2Rh2 tetrahedra, and edges with four equivalent O(2)Pt4Rh2 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF card [CIF]
