Abstract


Complexes [Ru(N,N,N-tris(benzimidazole-2-yl-methyl)amine-?N,N?,N?)Cl(PPh3)]Cl (1), [Ru(N,N-bis(benzimidazole-2-yl-methyl)hydroxyethylamine-?N,N?,N?)Cl(PPh3)]Cl (2) and [Ru(N,N,N-tris(2-aminoethyl)amine-?N,N?,N?)Cl(PPh3)]Cl (3) were synthesized by reaction of [Ru(PPh3)3Cl2] with N,N,N-tris(benzimidazole-2-yl-methyl)amine (L1), N,N-bis(benzimidazole-2-yl-methyl)hydroxyethylamine (L2) and N,N,N-tris(2-aminoethyl)amine (L3), respectively. The water soluble complex [Ru(N,N,N-tris(benzimidazole-2-yl-methyl)amine-?N,N?,N?)Cl(PTA)]Cl (4) was obtained by reaction of 1 with PTA (1,3,5-triaza-7-phosphinoadamantane). Complexes were characterized by IR, NMR and elemental analysis. The structure of 1 was determined by single crystal X-ray diffraction analysis. Photo- and electro-chemical behaviours evolution of the complexes were also done. The structural and electronic properties of 1, 2 and 3 were studied by DFT and DFT-TDDFT.
