Thermoanalytical Investigation of Magnesium(II) Complexes with Pyridine as Bio-Active Ligand

摘要: TG, DTA and other analytical methods were applied to investigate the thermal behaviour structures of compounds Mg(ClAc)2(Py)2·2H2O (I), Mg(Cl2Ac)2(Py)·H2O (II), Mg(Cl3Ac)2(Py)·6H2O (III) Mg(SCN)2(Py)3·2H2O (IV), where ClAc=ClCH2COO−, Cl2Ac=Cl2CHCOO−, Cl3Ac=Cl3CCOO− Py=Pyridine. The compositions complexes solid-state intermediates products thermolysis identified by means elemental analysis. Possible schemes destruction are suggested. final decompositions MgO (I–III) MgS (IV). IR data suggest unidentate coordination carboxylate ions Mg(II) in I–III. Py is coordinated through nitrogen atom its heterocyclic ring.
