metal-to-ligand stoichiometric formulae [M(HL)(OAc)2(OH2)2] (MCu(II)(1), Co(II)(2), Ni(II)(3) and Cd(II)(4)), octahedral configuration and the ligand behaves as a neutral bidentate forming six-membered chelating ring towards the metal ions, bonding through azomethine nitrogen and ketonic oxygen atoms. The molecular structures of the ligand and its metal complexes were also studied using quantum chemical
制备了3-[(2-羟基-3-甲氧基亚苄基))]-1,3-二氢吲哚-2-酮(HL)的金属(II)配合物,在元素分析的基础上表征了其组成和理化性质,摩尔电导率,1 H NMR,UV-Vis,IR,质谱,X射线,磁测量和热重分析(TGA)。所有结果证实,该新型配合物具有1:1的金属配体化学计量公式[M(HL)(OAc)2(OH 2)2 ](M Cu(II)(1),Co(II)(2) ,Ni(II)(3)和Cd(II)(4)),八面体构型和配体表现为中性双齿,形成朝向金属离子的六元螯合环,并通过偶氮甲碱氮和酮氧原子键合。还使用量子化学计算研究了配体及其金属配合物的分子结构,结果表明具有氢键的酮形式比其他形式更稳定。周围的所有络合物(配位几何1 - 4)显示的八面体几何形状。XRD研究表明,配体和Cu(II)配合物均显示具有三斜晶系的多晶。活化热力学参数,例如活化能(E a),使用Coats–Red
