The compound described by Ru2Ir2O5 crystallizes in the tetragonal P4/mmm space group. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a body-centered cubic geometry to eight equivalent Ir(1) atoms. In the second Ru site, Ru(2) is bonded to four equivalent O(2) and eight equivalent O(1) atoms to form a mixture of face and corner-sharing RuO12 cuboctahedra. Ir(1) is bonded in a 4-coordinate geometry to four equivalent Ru(1) and four equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Ru(2) and two equivalent Ir(1) atoms to form a mixture of corner and edge-sharing OIr2Ru2 tetrahedra. In the second O site, O(2) is bonded in a square co-planar geometry to four equivalent Ru(2) atoms. is represented by the CIF card [CIF]
