Complexes of Cr(III), Co(II), Ni(II) and Cu(II) containing a novel macrocyclic tetradentate nitrogen donor (N4) ligand prepared via reaction of 2,3-hexanedione and ethylenediamine has been prepared and characterized. The newly synthesized ligand (L) and its complexes have been characterized on the basis of elemental analysis, molar conductance, magnetic moment susceptibility, EI-Mass, IR, Electronic and EPR spectral studies. The complexes are of high-spin type and four coordinated tetrahedral, five coordinated square pyramidal and six coordinated octahedral/tetragonal geometries. The ligand (L) and its soluble transition metal complexes have also been screened against different bacteria and plant pathogenic fungi in vitro.
通过2,3 - 己二酮与乙二胺反应制备了含有新型大环四齿氮供体（N4）配体的Cr(III)、Co(II)、Ni(II)和Cu(II)配合物，并对其进行了表征。新合成的配体（L）及其配合物通过元素分析、摩尔电导率、磁矩磁化率、电子轰击质谱、红外光谱、电子光谱和电子顺磁共振光谱研究进行了表征。这些配合物为高自旋型，具有四配位四面体、五配位四方锥和六配位八面体/四方几何构型。配体（L）及其可溶性过渡金属配合物还在体外针对不同细菌和植物病原真菌进行了筛选。
