摘要：

The new mixed ligand complexes with the formulae Zn(2-bipy)(ox), Zn(4-bipy)(1.5)(ox)H2O, Zn(2,4'-bipy)(2)(ox)2H(2)O, Cd(2-bipy)(ox)2H(2)O, Cd(4-bipy)(2)(ox) and Cd(2,4'-bipy)(ox)2H(2)O (2-bipy, 4-bipy, 2,4'-bipy=2,2'-, 4,4'- and 2,4'bipyridine, ox=oxalate) were prepared. The thermal decompositions of these compounds were studied by means of TG, DTG and DTA in air. During heating the complexes decompose via different intermediate products to ZnO and CdO. The Zn(II) complexes are thermally more stable than the corresponding Cd(II) complexes. The influence of nitrogen atom position in the bipyridine isomers and nature of central atom on the thermal behaviour of these complexes was discussed.
