By reacting different copper(II) salts with uridine and cytidine in ethyl acetate, several mononuclear copper(II) complexes have been obtained. The complexes are pale in colour and exhibit hygroscopic behaviour. Both nucleosides coordinate in molecular form through a carbonyl group and through the nitrogen atom of the pyrimidine ring for uridine and cytidine, respectively, resulting in a weak ligand field. The spectroscopic data of the complexes and their thermal study using TG and DSC techniques are reported. © 1993.
