Abstract
The compounds Cu2(RCO2)4 and Cu2(RCO2)4py2 [R=CH3(CH2)n−2; n=14, 16, 18; py=pyridine] were prepared, analysed and characterized by means of DSC calorimetry, thermogravimetry and infrared spectroscopy. Generally, the pyridine complexes are unstable, losing pyridine already at room temperature. Transition from a crystalline to a liquid crystalline phase after heating was observed for all Cu2(RCO2)4 compounds but only for pyridine complex of Cu(II) tetradecanoate. However, the melting process was observed for all Cu(II) carboxylate complexes with pyridine. The lower thermal stability of pyridine complexes, than corresponding Cu2(RCO2)4 compounds can be explained by structural features.
