electrochemical properties. The molar conductance of all the complexes in DMSO solution is corresponding to 1:2 electrolyte. Thus these complexes may be formulated as [M(L′)]Cl2 [where M = Mn(II), Co(II), Ni(II) and Cu(II) L′ = L1 and L2]. On the basis of spectral studies a distorted octahedral geometry has been assigned for all the complexes. The ligands and their complexes were also screened in vitro
Mn(II),Co(II),Ni(II)和Cu(II)配合物已经合成,具有22和24元四酰亚胺大环配体。1,9,12,20-tetraaza-2,8,13,19-tetraone-5,16-dithiacyclodocosane [L 1 ]和1,9,13,21-tetraaza-2,8,14,20-tetraone- 5,17-二噻吩并环四烷[L 2 ],其特征在于元素分析,摩尔电导,磁化率测量,质量,IR,电子EPR光谱研究和电化学性质。DMSO溶液中所有络合物的摩尔电导对应于1:2的电解质。因此,这些配合物可配制成[M(L')] Cl 2 [其中M = Mn(II),Co(II),Ni(II)和Cu(II)L'= L 1和L 2]。在光谱研究的基础上,为所有配合物分配了扭曲的八面体几何形状。配体和它们的复合物还筛选体外针对两种病原真菌(F. moniliformae和R. 菌),以评估其生长抑制潜力。
