| Abstract: | The thermal decomposition of the complexes Mg(Clac)2 (ron)2 ×3H2 O(I), Mg(Cl2 ac)2 (ron)2 ×3H2 O(II) and Mg(Cl3 ac)2 (ron)2 ×3H2 O(III), where Clac =ClCH2 COO- , Cl

ac =Cl2 CHCOO- , Cl

ac =Cl3 CCOO- and ron =3-pyridylcarbinol (ronicol) had been investigated in air atmosphere in temperature range 20–1000°C by means of TG and DTA.
The composition of the complexes and the solid state intermediate and resultant products of thermolysis had been identified
by means of elemental analysis and complexometric titration. The possible scheme of destruction of the complexes is suggested.
The final product of the thermal decomposition was MgO. The thermal stability of the complexes can be ordered in the sequence:
I<III<II. IR data suggest that ronicol was coordinated to Mg(II) through the nitrogen atom of its heterocyclic ring.
