SOLID, PRIMARY ALIPHATIC AMINE COMPLEXES OF TRANSITION-METAL HALIDES .2. THERMAL-ANALYSIS STUDIES OF RNH2 COMPLEXES OF CADMIUM(II) CHLORIDE

The thermal decomposition of some new primary aliphatic amine RNH2 (R =methyl-, ethyl-, n-propyl, i-propyl, n-butyl-, i-butyl-, n-amyl-, i-amyl-, cyclohexyl- and i-allyl-) complexes with cadmium(II) chloride, prepared by solid-gas phase chemisorption, have been investigated by simultaneous TG-DTG-DTA. The enthalpy changes during the degradation were followed by DSC. The course of the thermal decomposition is described in detail. The thermal properties observed were compared to the more recently reported nickel(II) analogues. The changes in thermal parameters in the series of cadmium(II) chloride aliphatic amine complexes are discussed on the basis of the inductive releasing effect of the aliphatic chain and the steric hindrance of the ligands.
