Studies on coordination compounds vii, chromatographic, thermoanalytical and spectroscopic studies on thermal decomposition of cadmium(II) and lead(II) salicyl-aldoximates

The reaction products of five substituted 2-hydmxyaryloximes with Fe(III) ion were obtained and characterized by means of elemental analysis, conductometric measurements, magnetic moment determinations and spectroscopic data (IR and electronic absorption).The thermal stability and mode of decomposition were studied in air atmosphere by using TG-DTA. Kinetic analysis of the TG data was performed with the Coats-Redfern method to determine the apparent activation energies and the pre-exponential factor of the Arrhenius equation. Mass spectrometry was also used, and possible fragmentation patterns are given and discussed.

The following Zn(ll)complexes of deprotonated 6oamino-5-nitrosouracil (AH), 6-amino--3-methyl-5-nitrosouracil (BH) and 6-amino-l-methyl-5-nitrosouracil (CH) have been prepared and their thermal behaviour studied by TG and DSC techniques: ZnA2(H20) 2, ZnB 2 9 4 H20, ZnC 2 , 4 H20 and ZnC2(H20) 2 9 H20. The values of the dehydration enthalpy of the complexes are in the 31.3-76.5 kJ tool-t H20 range and, except in the first complex, the dehydration processes take place in several steps. The pyrolysis of the complexes finishes between 540 and 725 ~ C ZnO remaining as residue.
