| Abstract: | The treatment of optically P-chiral tetraphosphine, (3S,6R,9R,12S)-6,9-di-tert-butyl-2,2,3,12,13,13-hexamethyl-3,6,9,12-tetraphosphatetradecane (1), with rhodium(I), palladium(II), and ruthenium(II) complex precursors led to the selective formation of mono-, di-, or trinuclear homo- or heterometallic complexes, Rh(1)]SbF6 (4), {Rh(nbd)}2(1)](SbF6)2 (3), {Pd(η3-allyl)}2(1)](SbF6)2 (5), {RuCl(η5-C5(CH3)5)}2(1)] (6), and {RuCl2(η6-benzene)}2(PdCl2)(1)] (8). These complexes were characterized by NMR and X-ray crystallographic analysis. |
