摘要：

Synthesis and characterisation of ruthenium(II) complexes of several alpha-N heterocyclic carboxylic acids of the general formula [Ru(PPh3)(2)(L)(2)] are reported [LH = pyridine 2-carboxylic acid ((LH)-H-1), pyrazine 2-carboxylic acid ((LH)-H-2), imidazole 4,5-dicarboxylic acid ((LH2)-H-3) and pyrazine 2,3-dicarboxylic acid ((LH2)-H-4)]. All the acids behaved as bidentate N-O chelating donors, the second carboxyl group of the dicarboxylic acids remaining free. Electrochemical behaviour of the complexes was explored by cyclic voltammetry. Single-crystal X-ray analysis of the two complexes cis-[Ru(PPh3)(2)(L-1)(2)].2CH(3)OH and cis-[Ru(PPh3)(2)((LH)-H-3)(2)] led to the elucidation of the structures and showed that in both the complexes the two bulky PPh3 groups were cis to each other.
