Synthesis and characterisation of ruthenium(II) complexes of several α-N heterocyclic carboxylic acids of the general formula [Ru(PPh3)2(L)2] are reported [LH = pyridine 2-carboxylic acid (L1H), pyrazine 2-carboxylic acid (L2H), imidazole 4,5-dicarboxylic acid (L3H2) and pyrazine 2,3-dicarboxylic acid (L4H2)]. 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(L1)2] ·2CH3OH and cis-[Ru(PPh3)2(L3H)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.
