The reaction of the ammonia diol [(NH3)4Rh(OH)2Rh(NH3)4]4+with H2O2 Yields among other products a peroxo-bridged dimeric species [(NH3)4Rh(O2)(OH)Rh(NH3)3(H2O)](CIO4)3. Its structure was determined by single-crystal X-ray diffraction. The crystals are monoclinic with space group P21/n and lattice constants a=12.269 (5) Å, b=10.769(4) Å, c=15.964(4) Å, β=107.17(3)°. The dihedral angle of the RhOORh group in the bimetallic ring deviates by 62δ from planarity. The peroxo-bridged complex was found to disproportionate in 1M HCIO4 and a red superoxo-bridged complex. [(NH3)4Rh(O2)(OH)Rh(NH3)3(H2O)](NO3)4, was isolated. Its structure was solved by single-crystal X-ray diffraction. The crystals are orthorhombic with space group Pna 2, and lattice constants a=14.997(5) Å, b=11.952(4) Å, C=10.489(4) Å. The dihedral angle off the RhOORh group deviates by 7δ from planarity.
