| Abstract: | Homopolynuclear complexes of Cu(II) respectively Cr(III) with the glyoxylate dianion, C2H2O4 2-, have been studied in non-isothermal regime in air and nitrogen. The results of the non-isothermal analysis performed for the synthesised complexes, Cu(C2H2O4)·0.5H2O, respectively [Cr2(OH)2(C2H2O4)2(OH2)4]·2H2O, correlated with the results of the IR and TG analysis of the compounds obtained by thermal treatment from the initial complexes and the results of the GLC and XR analysis have led to the establishment of the thermal decomposition mechanisms for the two studied complexes. The decomposition mechanisms confirm the stoichiometric and structural formulae proposed for the two synthesised homopolynuclear complexes. This revised version was published online in July 2006 with corrections to the Cover Date. |
