Abstract
Solid state ML where M stands for bivalent transition metals MnII FeII CoII NiII CuII and ZnII and L is mandelate were synthesized Simultaneous thermogravimetry and differential scanning calorimetry elemental analysis and complexometry were used to establish the stoichiometry and to study the thermal behaviour of these compounds in CO2 and N2 atmospheres The results show that all the compounds were obtained in the anhydrous state and in agreement with the general formula ML2 The thermal decomposition of the compounds occurs in a single CuII two NiII three FeII CoII four MnII and five ZnII steps The results also provided information concerning the ligand’s denticity thermal behaviour final residues and identification of gaseous products evolved during the thermal decomposition of these compounds
