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-a myl-, cyclohexyl- and i-allyl-) complexes with cadmium(II) chloride, p repared by solid-gas phase chemisorption, have been investigated by si multaneous TG-DTG-DTA. The enthalpy changes during the degradation wer e followed by DSC. The course of the thermal decomposition is describe d in detail. The thermal properties observed were compared to the more recently reported nickel(II) analogues. The changes in thermal parame ters in the series of cadmium(II) chloride aliphatic amine complexes a re discussed on the basis of the inductive releasing effect of the ali phatic chain and the steric hindrance of the ligands.
