| 摘 要： | 以4-氨基-1,2,4-三氮唑与对羟基苯甲醛为原料,在冰醋酸催化下合成了配体4-氨基-1,2,4-三氮唑缩对羟基苯甲醛(L)。然后利用4-氨基-1,2,4-三氮唑缩对羟基苯甲醛(L)与过渡金属硝酸盐RE(NO_3)_2·xH_2O(RE=Cu,Co,Zn,Cd;x=3～6)]在无水乙醇中反应,制得固态配合物RE_3L_6(NO_3)6(H_2O)_2。通过元素分析、红外光谱、紫外光谱、荧光光谱等手段对合成的配体及配合物进行了表征。结果表明,RE_3L_6(NO_3)_6(H_2O)_2与RE(Ⅱ)发生配位作用的基团是配体中三氮唑环上的氮原子。

| Abstract: | Schiff base 4-(4-Hydroxybenzaldehyd eamino)-4H-1,2,4-triazole(L)were synthesized from 4-Amino- 1,2,4-triazole and p-Hydroxybenzaldehyde using acetic acid as the catalyst.The solid complexes RE_3L_6(NO_3)_6 (H_2O)_2(RE=Cu,Co,Zn,Cd;x=3～6)were synthesized with 4-(4-Hydroxybenzaldehydeamino)-4H-1,2,4-triazole and nitrate of transition metals in ethanol and characterized by elemental analysis,Infrared spectroscopy,UV spectrum,Fluorescence spectrum.The results showed that RE(Ⅱ) was coordinated with N atomy of triazole in 4-(4- Hydroxybenzaldehydeamino)-4H-1,2,4-triazole. |
