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

Abstract

Mononuclear hydri do carbonyl complex [RuH(CO)(PPh₃)₂-(η²-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(η⁶-arene)(µ-Cl)CI}₂] (arene = <i style="mso-bidi-font-style:normal">p</i>-cymene or benzene), [{Rh(η⁵-C₅Me₅) (µ-Cl)Cl}₂] and [Rh(COD)(µ-Cl)]₂ (COD) = 1.5 cyclooctadiene) leads to the formation of binuclear complexes. The homo and hetero binuclear tptz bridged complexes complex [RuH(CO)(PPh₃)₂(µ-tptz)PdCl₂]BF₄,

[RuH(CO)(PPh₃)₂(µ-tptz)PdCl₂]BF₄, [RuH(CO)(PPh₃)₂(µ-tptz)-(η⁶-C₁₀ H₁₄)RuCl(BF₄)₂, [RuH(CO)(PPh₃)₂(µ-tptz)(η⁶-C₆Me₆)-RuCl(BF₄)₂, [RuH(CO)(PPh₃)₂(µ-tptz)(η²-COD)RH](BF₄)₂and [RuH(CO)(PPh₃)₂(µ-tptz)(η⁵-C₅Me₅)Cl](BF₄)₂ have been synthesized and characterized using IR, NMR, ESMS and FAB mass spectra.
