Zn complexes of Schiff base ligands derived from 2,2'‐diaminobiphenyls and salicylaldehyde derivatives were synthesized and characterized by NMR and single‐crystal X‐ray diffraction analysis. The detailed NMR studies suggest that the Zn complexes have a complicated behavior in solution, which is strongly dependent on the donating ability of the solvent, the steric properties of the ligand, as well
合成了由2,2'-二氨基联苯和水杨醛衍生物衍生的席夫碱配体的锌配合物,并通过NMR和单晶X射线衍射分析进行了表征。详细的NMR研究表明,Zn络合物在溶液中具有复杂的行为,这在很大程度上取决于溶剂的供电能力,配体的空间性质以及溶剂中络合物的浓度。所有这些因素对于确定溶液中配合物的配位数至关重要。此外,合成了通过一系列氮碱连接的上述类型的五配位Zn络合物。在不同浓度和温度下对不同络合物的NMR研究表明,它们的构象稳定性有关。通过单晶X射线衍射分析进一步检查了差异。除了对锌络合物的研究以外,对一系列镉络合物进行了比较研究。
