The thermal decomposition of the complexes Mg(Clac)2(pic)2×3H20 (I), Mg(Cl2ac)2(pic) × 4H20 (II) and Mg(Cl3ac)2(pic)2 × 3H2O (III), where Clac = ClCH2COO-, Cl2ac = Cl2CHCOO-, Cl3ac = Cl3CCOO- and pic = g-picoline had been investigated in air by TG and DTA. The possible scheme of destruction of the complexes is suggested. The final product was MgO for the complex I-III. The thermal stability of the complexes can be ordered in the sequence: I = III < II. IR data suggest a unidentate coordination of carboxylates to Mg (II) in complexes I-III and g-picoline coordination with Mg(II) through the nitrogen atom of its heterocyclic ring.
