energetics of the ligands and their complexes. Molecular Electrostatic Potential was also calculated by the DFT method and predicts the most reactive part in the molecule. The isolated complexes are found to have the formulas [Cu(L1)2] a1, [Co(L1)2] a2, [Fe(L1)3] a3, [Cu(HL2)2Cl2].H2O b1, [Co(HL2)(NO3)2].H2O b2, [Fe(HL2)Cl3].H2O b3, [Cu(HL3)Cl2].H2O c1, [Co(HL3)(NO3)2].H2O c2 and [Fe(HL3)Cl3].H2O c3
三种偶氮化合物的 Fe(III)、Co(II) 和 Cu(II) 配合物,即 2-(苯偶氮)-1-萘酚 (苏丹 I) (HL 1 ) a、4-(苯偶氮)-1-萘酚(HL 2 ) b和 2,4-双(苯偶氮)-1-萘酚 (HL 3 ) c在元素分析、摩尔电导、UV-VIS 和 FT IR 光谱研究的基础上进行了制备和表征。此外,还进行了密度泛函理论 (DFT) 计算来研究配体及其配合物的结构和能量学。分子静电势也通过 DFT 方法计算并预测分子中最具反应性的部分。发现分离的配合物具有公式 [Cu(L 1 ) 2] a1 , [Co(L 1 ) 2 ] a2 , [Fe(L 1 ) 3 ] a3, [Cu(HL 2 ) 2 Cl 2 ].H 2 O b1, [Co(HL 2 )(NO 3 ) 2 ].H 2 O b2, [Fe(HL 2 )Cl 3 ].H 2 O b3, [Cu(HL 3 )Cl
