报道了配合物Ln(X-P)_3·3H_2O[其中X=H,2-Cl,4-Br,3-OH,3-NO_2,2-OCH_3,2-CH_3,2,4-二氯,P=2-(COO)C_6H_4CONHC_6H_(5-n)X_n,n=1,2;Ln=Pr(Ⅲ),Nd(Ⅲ)]的制备,并用元素分析、红外光谱、电子反射光谱、热重分析进行了表征。结果表明,配位是通过羧酸羟基氧原子和酰胺羰基氧原子进行的,含3分子配位水。通过电子反射光谱数据,对Slater-Condon参量(F_k)、Lande参量(ξ_(4f))、Nephelauxit比率(?),平均共价参数(?)、平均成键参数(?)、F_4/F_2、F_6/F_2比值进行了计算,对配合物的共价成键情况进行了讨论。
Reported that the complex Ln (XP) _3 · 3H_2O [wherein X = H, 2-Cl, 4-Br, 3-OH, 3-NO_2, 2-OCH_3,2-CH_3,2,4-dichloro, P = The preparation of 2- (COO) C_6H_4CONHC_6H_ (5-n) X_n, n = 1,2; Ln = Pr (Ⅲ), Nd (Ⅲ)] was studied and characterized by elemental analysis, FTIR, Characterization. The results show that the coordination through the carboxylic acid hydroxy oxygen atoms and amide carbonyl oxygen atoms, containing three molecules coordination water. Based on the electron reflectance spectroscopy data, the parameters of Slater-Condon parameter, Lande parameter (ξ_ (4f)), Nephelauxit ratio ()), average covalent parameter ()), average bonding parameter ()), F_4 / F_2, F_6 / F_2 ratio were calculated, the covalent bonding of the complexes were discussed.
