Abstract  

A series of new complexes with mixed ligands of the type [ML(C3H3O2)2nH2O (((1)M=Mn, n=1; (2)M=Co(II), n=2; (3)M=Ni(II), n=4; (4)M=Cu(II), n=1.5; (5)M=Zn(II), n=0; L=3-amino-1,2,4-triazole and (C3H3O2)=acrylate anion) were synthesized and characterised by chemical analysis and IR data. In all complexes the 3-amino-1,2,4-triazole acts as bridge while the acrylate acts as bidentate ligand except for complex (5) where it is found as unidentate. The thermal behaviour steps were investigated in nitrogen flow. The thermal transformations are complex processes according to TG and DTG curves including dehydration, acrylate ion and 3-amino-1,2,4-triazole degradation respectively. The final products of decomposition are the most stable metal oxides, except for complex (4) that leads to metallic copper.
