N2 - The complexes Δ,Λ-[Co(1,10-phenanthroline)2-(oxyacidate)]·ClO4·3 1 2H2O, where oxyacidate is S(-)malate(2-) and R,R-(+)-tartrate(2-) have been synthesised, the diastereoisomers separated, and characterized. High resolution 1H NMR spectroscopy indicates that intramolecular hydrogen bonding may be responsible for the stabilities of the various diastereoisomers both in aqueous solution and in the solid state. The ratios of diastereoisomers obtained do not reflect thermodynamic equilibrium, and solubility phenomena may give rise to the patterns of isomeric distribution found here, and by other workers.
