Schiff base namely, N,N′-bis[1,3benzodioxol-5-ylmethylene] ethane-1,2-diamine was synthesized by condensing piperonaldehyde (3,4-dioxymethylenebenzaldehyde) with ethylenediamine. Cr(III), Mn(II), Fe(III), Co(II), Ni(II) and Cu(II) complexes of this chelating/bridging ligand were synthesized using acetates, chlorides, bromides, nitrates and perchlorates of these metals. The ligand and the complexes were characterized
通过将戊醛(3,4-二甲醛)与乙二胺缩合来合成二齿/四齿席夫碱,即N,N'-双[1,3苯并二恶唑-5-基亚甲基]乙烷-1,2-二胺。该螯合/桥联配体的Cr(III),Mn(II),Fe(III),Co(II),Ni(II)和Cu(II)络合物是使用这些化合物的乙酸盐,氯化物,溴化物,硝酸盐和高氯酸盐合成的金属。配体和配合物通过元素分析表征11 H NMR,UV-vis和IR光谱,电导率和磁化率测量以及热重分析。配体在其某些配合物中显示出桥联性质,如磁性和微观分析数据所证明。分析了三种配合物的热谱图,并确定了不同分解阶段的动力学参数。在胡萝卜琼脂培养基中测试了配体及其某些复合物对辣椒疫霉菌的抗真菌活性。
