The synthesis of a series of asymmetric mixed 2,6-disubstituted (arylcarboxamido)(arylimino)pyridine ligands and their coordination chemistry toward a series of divalent first-row transition metals (Cu, Co, and Zn) have been explored. Complexes featuring both anionic N,N′,N″-carboxamido and neutral O,N,N′-carboxamide coordination have been prepared and characterized by X-ray crystallography, cyclic
已经探索了一系列不对称混合 2,6-二取代(芳基甲酰氨基)(芳基亚氨基)吡啶配体的合成及其对一系列二价第一排过渡金属(Cu、Co 和 Zn)的配位化学。已经制备了具有阴离子N , N ', N '-甲酰胺和中性O , N , N '-甲酰胺配位的配合物,并通过 X 射线晶体学、循环伏安法、紫外-可见光和 EPR 光谱对其进行了表征。具体而言,R LM(X) (M = Cu; X = Cl – , OAc – ) 和R L(H)MX 2 (M = Cu, Co, Zn; X = Cl –,的SbF 6 - ),其设有配合Ñ,Ñ ',ñ “ -或Ó,Ñ,Ñ '-coordination被呈现。从O , N , N '-甲酰胺到N , N ', N '-甲酰胺配位的碱基诱导的连接异构化也通过多种形式的光谱学得到证实。
