The isonicotinic acid adduct [Ru(η3:η3-C10H16)Cl2(p-NC5H4CO2H)] 1 and nicotinate and isonicotinate bridged binuclear complexes [Ru2(η3:η3-C10H16)2Cl3(μ-κN,O,O′-NC5H4CO2)] 2 and 3 are reported. Complexes 2 and 3 exist as mixtures of diastereoisomers and are dynamic in water saturated chloroform solution with complexes involving bidentate chelating carboxylate ligands in equilibrium with unidente carboxylate aquo complexes [Ru2(η3:η3-C10H16)2Cl3(OH2)(μ-κN,O-NC5H4CO2)].
