N2 - The reaction of (Ru3(CO)12) with bis(diphenylphosphino)amine (dppa) in the presence of sodium benzophenone leads to (Ru3(CO)10(dppa)) in quantitative yield, while the same reaction carried out in refluxing toluene also produces the disubstituted product (Ru3(CO)8(dppa)2). Both products were characterized spectroscopically and by X-ray crystallography. The five-membered rings, formed by the coordinated ligand and the two metal atoms, show distorted envelope conformations. There are significant differences in the P-N bond lengths of each dppa ligand in the disubstituted cluster while they are totally symmetric in the monosubstituted derivative.
