Abstract

Thermogravimetry (TG), differential thermal analysis (DTA) and other analytical methods have been applied to the investigation of the thermal behaviour and structure of the compounds Mg(Ac)2 × 2H2 O(I), Mg(ClAc)2 ×2H2 O(II) and Mg(Cl2 Ac)2 ×H2 O(III) (Ac =CH3 COO , ClAc =ClCH2COO , Cl 2 Ac =Cl2 CHCOO ). The solid phased intermediate and resultant products of thermolysis had been identified. The possible scheme of destruction of the complexes is suggested. The halogenacetato magnesium complexes (II–III) are thermally more stable than the acetatomagnesium complex I. The final products of the decomposition of compounds were MgO. Infrared (IR) data suggest to a unidentate coordination of carboxylate ions to magnesium ions in complexes I–III.
