The paper presents the synthesis and physico-chemical characterization of some Mn(II), Co(II), Ni(II) and Cu(II) complexes with N-p-nitrobenzoyl-a-phenylalanine and the determination of toxicity level (lethal dose). Elemental analysis, FTIR, UV-visible and XRD spectroscopy, electronic spin resonance (ESR), Mössbauer spectroscopy for the iron compound and the thermal stability with the FTIR analysis of the evolved gases were applied to characterize the metal complexes. All the compounds have an orthorhombic crystalline structure and have a thermal stability over 100 °C. The toxicity of the new compounds was tested on laboratory mice and was determined that Cu(II) compound has the lowest lethal dose compared with the pure ligand.
本文介绍了一些锰(II)、钴(II)、镍(II)和铜(II)与 N-对硝基苯甲酰-a-苯丙氨酸配合物的合成、物理化学特征以及毒性水平(致死剂量)的测定。为表征金属络合物的特性,采用了元素分析、傅里叶变换红外光谱、紫外可见光光谱和 XRD 光谱、电子自旋共振(ESR)、铁化合物的莫斯鲍尔光谱以及热稳定性和挥发气体的傅里叶变换红外光谱分析。所有化合物都具有正交晶状结构,热稳定性超过 100 °C。在实验室小鼠身上测试了新化合物的毒性,结果表明,与纯配体相比,铜(II)化合物的致死剂量最低。
