The clusters > 1 and > 2 containing the atropoisomeric diphosphine ligands (S)-(-)-2,2'-bis(diphenylphosphino)-1,1'-binaphthyl (binap) and (S)-(-)-2,2'-bis(diphenylphosphino)-6,6'-dimethoxy-1,1'-biphenyl (mobiph) have been synthesized via direct reaction of in toluene at 150 deg C with two-fold excess of the diphosphine under hydrogen pressure.Their molecular and crystal structures have been determined by single-crystal X-ray diffraction: both crystallize in the orthorhombic system, space group P212121, Z = 4; a = 13.009(7), b = 14.357(2), c = 29.109(7) Angstroem for 1; a = 12.108(8), b = 15.845(3), c = 28.241(5) Angstroem for 2.In both complexes the diphosphite ligand chelates the Ru atom involved in three hydride bridges.
