在15℃和—150℃下,用多通道恒加速穆斯堡尔谱仪测量了Fe(Ⅱ)-水杨醛肟(1)、Fe(Ⅱ)-2-羟基苯乙酮肟(2)、Fe(Ⅱ)-2-羟基二苯甲酮肟(3)及Fe(Ⅱ)-2-羟基-4-甲氧基二苯甲酮肟(4)的穆斯堡尔谱。解谱结果表明:配位体结构的电子效应对I.S.和Q.S.值影响不大,肟基碳原子上的氢(络合物(1))不论被推电子的甲基(络合物(2))或拉电子的苯基(络合物(3))取代后,~(57)Fe核上s电子密度无显著改变。这是因为这类络合物的稳定性
Fe (Ⅱ) -salicylaldoxime (1), Fe (Ⅱ) -2-hydroxyacetophenone oxime (2), Fe (Ⅱ) -2-hydroxybenzophenone oxime (3) and Fe (Ⅱ) -2-hydroxy-4-methoxybenzophenone oxime (4). The results of solution spectrum showed that the electronic effect of the ligand structure has little effect on the IS and QS values. Hydrogen ((1) ) Or the electron-withdrawing phenyl group (complex (3)), there is no significant change in the electron density on the ~ (57) Fe nucleus. This is because of the stability of such complexes
