杂环息夫碱化合物及其过渡金属配合物的合成与表征

SYNTHESIS AND CHARACTERIZATION OF THE HETEROCYCLIC SCHIFF BASE AND THEIR TRANSITION METAL COMPLEXES

本文合成了一种新的双齿(N,O)杂环息夫碱2-(2′-羟基)苯甲亚胺-5-(4′-硝基)偶氮苯吡啶(HL)与过渡金属的六种新配合物ML_2及M′L_3 [M=Mn(Ⅱ)、Co(Ⅱ)、Ni(Ⅱ)、Cu(Ⅱ)、Pd(Ⅱ);M′=Fe(Ⅲ)].采用元素分析、摩尔电导、红外光谱、紫外—可见光谱、磁化率以及热分析等研究了配合物的组成和性质.

A new Schiff base was synthesized by the condensation of equimolar quantities of salicylaldehyde and 2-amine-5-(4'-nitro) phenylazo-pyridine. Metal complexes of the type ML2, M'L3, where M = Cu(Ⅱ),Co(Ⅱ),Ni(Ⅱ), Mn(Ⅱ ), Pd(Ⅱ), M' = Fe(Ⅲ) and L = newly synthesized monobasic Schiff base were prepared in absolute ethanolic medium and characterized by elemental analysis, molar, conductance, infrared spectra, electronic spectra, magnetic moments and thermal analysis studies.
