A series of new complexes with mixed ligands of the type [ML(C3H3O2)2]·nH2O (((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.
合成了一系列具有[ML(C3H3O2)2]-nH2O(((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-氨基-1,2,4-三唑和 (C3H3O2)= 丙烯酸酯阴离子)进行了合成,并通过化学分析和红外数据进行了表征。在所有络合物中,3-氨基-1,2,4-三唑起桥作用,而丙烯酸酯起双齿配体作用,只有络合物(5)除外,它是非双齿配体。在氮气流中对热行为步骤进行了研究。根据 TG 和 DTG 曲线,热转化过程十分复杂,分别包括脱水、丙烯酸酯离子和 3-氨基-1,2,4-三唑降解。分解的最终产物是最稳定的金属氧化物,但络合物 (4) 除外,会生成金属铜。
