Synthesis and characterization of some homo/hetero binuclear hydrido carbonyl ruthenium(II) polypyridyl complexes

Mononuclear hydrido carbonyl complex [RuH(CO)(PPh3)(2)-(eta(2)-tptz)]BF4 (tptz = 2,4,6-tris-(2'-pyridyl)-1,3,5-triazine) has been used as a building block in the synthesis of homo/hetero binuclear complexes. The complex [RuH(CO)(PPh3)(2)(tptz)]BF4 behaves as a potential metallo-ligand. Its reaction with different molecules ranging from K2PtCl4, [PdCl2(PhCN)(2)], chloro-bridged dimeric arene ruthenium complexes [{Ru(eta(6) -arene)( mu-Cl)Cl}(2)] (arene = p-cymene or benzene), [{Rh(eta(5)-C5Me5)(mu-Cl)Cl}(2)] and [Rh(COD)(mu-Cl)](2) (COD = 1,5-cyclooctadiene) leads to the formation of binuclear complexes. The homo and hetero binuclear tptz bridged complexes [RuH(CO)(PPh3)(2)(mu-tptz)PtCl2]BF4, [RuH(CO)(PPh3)(2)(mu-tptz)PdCl2]BF4, [RuH(CO)(PPh3)(2)(mu-tptz)- (eta(6)-C10H14)RuCl](BF4)(2), [RuH(CO)(PPh3)(2)(mut-tptz)(eta(6)-C6Me6)RuCl](BF4)(2), [RuH(CO)(PPh3)(2)(mu-tptz)(eta(2)-COD)Rh](BF4)(2) and [RuH(CO)(PPh3)(2)(mu-tptz)Rh(eta(5) -C5Me5)Cl](BF4)(2) have been synthesized and characterized using IR, NMR, ESMS and FAB mass,spectra.
