Abstract

Graphical abstract: Nicotinic acid bridged binuclear ruthenium(IV) complexes are dynamic with complexes involving bidentate chelating carboxylate ligands in equilibrium with unidente carboxylate aquo complexes. Abstract: The isonicotinic acid adduct [Ru(η 3 :η 3 -C10 H16 )Cl2 ( p -NC5 H4 CO2 H)]1 and nicotinate and isonicotinate bridged binuclear complexes [Ru2 (η 3 :η 3 -C10 H16 )2 Cl3 (μ-κ N, O, O′ -NC5 H4 CO2 )]2 and3 are reported. Complexes2 and3 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 (η 3 :η 3 -C10 H16 )2 Cl3 (OH2 )(μ-κ N, O -NC5 H4 CO2 )].
