Treatment of [(η⁶-C₆H₆)RuCl₂]₂ or [(η⁶-p-cymene)RuCl₂]₂ with two equiv. of L-methionine in the presence of AgNO₃ and NaOMe gave mononuclear ruthenium(II) complexes [(η⁶-C₆H₆)Ru(L-met)](NO₃) (1) and [(η⁶-cymene)Ru(L-met)](NO₃) (2), respectively. Interactions between equal equiv. of L-methionine and [Ru(CO)₂Cl₂]_n, [Ru(bpy)₂Cl₂]·2H₂O (bpy = 2,2′-bipyridine), [Ru(NO)(PPh₃)₂Cl₃], (Et₄N)[Ru(CH₃CN)₂Cl₄] or cis-[Ru(DMSO)₄Cl₂] (DMSO = dimethylsulfoxide) resulted in isolation of the expected ruthenium complexes [(CO)₂Ru(L-met)Cl] (3), [(bpy)₂Ru(L-met)]Cl (4), [Ru(L-met)(NO)(PPh₃)Cl]Cl (5), [Ru(L-met)(CH₃CN)Cl₂] (6) and [Ru(L-met)(DMSO)₂Cl] (7), respectively. Reaction of [Ru(COD)Cl₂]₂ (COD = 1,5-cyclooctadiene) with L-methionine gave a dinuclear ruthenium complex [(COD)Ru(μ-S-L-met)(μ-Cl)RuCl(L-metNMe₂)] (8). Complexes 1−8 were characterized by microanalyses, IR, NMR and UV–vis spectroscopies. The structures of complexes 1, 2, 4 and 8 have been unambiguously established by single-crystal X-ray crystallography. The photocatalytic properties for hydrogen production by water splitting of complexes 1, 2, 4 and 8 under visible light (λ > 420 nm) were also investigated.
