Abstract

The new zinc(II) complexes of general formula Zn(CH3CH2CH2COO)2· nL (whereL = caffeine, nicotinamide, theobromine;n=1 or 2) were prepared and identified.

Thermal properties of these compounds were investigated by thermal analysis (TG/DTG, DTA, DSC/DDSC).

Gaseous products of thermal decomposition were detected by IR spectroscopy and Mass spectroscopy. Final products of thermal decomposition were determined by X-ray powder diffraction patterns.
