  Study of half-sandwich platinum group metal complexes bearing dpt-NH2 ligand

  摘要：

  A quite general approach for the preparation of eta(5)-and eta(6)-cyclichydrocarbon platinum group metal complexes is reported. The dinuclear arene ruthenium complexes [(eta(6)-arene)Ru(mu-Cl)Cl](2) (arene=C6H6, C10H14 and C6Me6) and eta(5)-pentamethylcyclopentadienyl rhodium and iridium complexes [(eta(6)-C5Me5)M(mu-Cl)Cl](2) (M = Rh, Ir) react with 2 equiv. of 4-amino-3,5-di-pyridyltriazole (dpt-NH2) in presence of NH4PF6 to afford the corresponding mononuclear complexes of the type [(eta(6) -arene)Ru(dpt-NH2)Cl]PF6 {arene = C10H14 (1), C6H6 (2) and C6Me6 (3)} and [(eta(6)-C5Me5)M(dpt-NH2)Cl]PF6 {M = Rh (4), Ir (5)}. However, the mononuclear eta(5)-cyclopentadienyl analogues such as [(eta(5)-C5H5)Ru(PPh3)(2)Cl], [(eta(5)-C5H5)Os(PPh3)(2)Br], [(eta(5)-C5Me5)Ru(PPh3)(2)Cl] and [(eta(5)-C9H7)Ru(PPh3)2Cl] complexes react in presence of I equiv. of dpt-NH2 and I equiv. of NH4PF6 in methanol yielded mononuclear complexes [(eta(5)-C5H5)Ru(PPh3)(dpt-NH2)]PF6 (6), [(eta(5)-C5H5)Os(PPh3)(dpt-NH2)]PF6 (7), [(eta(5)-C5Me5)Ru(PPh3)(dpt-NH2)]PF6 (8) and [(eta(5)-C9H7)Ru(PPh3)(dpt-NH2)]PF6 (9). respectively. These compounds have been totally characterized by IR, NMR and mass spectrometry. The molecular structures of 4 and 6 have been established by single crystal X-ray diffraction and some of the representative complexes have also been studied by UV-Vis spectroscopy.
