本文报道某些芳香族羟肟与过渡金属铜、镍、钴和铁的配合物的制备及它们的红外光谱研究. 配合物C=N的伸缩频率随配合物稳定常数的增大而提高,但无定量关系.在水杨醛肟与铜、镍、钴和铁的配合物中,ν_c=N值随金属原子电离势的降低而下降,且具线性关系. 配合物OH键的伸缩频率与形成配合物的构型有关.钻(Ⅱ)及铁(Ⅱ)的配合物是顺式构型,具有六元环的氢键桥,OH键的红外吸收为一宽而平坦的谱峰.铜(Ⅱ)及镍(Ⅱ)的配合物是反式构型,具有五元环的氢键桥,红外吸收较明显.ν_(OE)与配合物取代基的极性有关. 确定了配合物中M-O、M-N键的红外特征频率.测得了2-羟基-5-辛基二苯甲酮肟及2-羟基-4-仲辛氧基二苯甲酮肟与~(63)Cu及~(65)Cu的配合物的红外光谱同位素位移.
In this paper, the preparation of some aromatic hydroxyoxime complexes with transition metals copper, nickel, cobalt and iron and their IR spectra were studied. The stretching frequency of the complex C = N increased with the increase of the stability constant of the complex No quantitative relationship between the salicylaldoxime and copper, nickel, cobalt and iron complexes, ν c = N value decreases with the reduction of the metal atom ionization potential, and with a linear relationship.The complex OH bond stretching frequency and the formation of complexes The complex of diamond (Ⅱ) and iron (Ⅱ) is a cis configuration with six-membered ring hydrogen bond and the infrared absorption of OH bond is a broad and flat spectrum. And nickel (Ⅱ) complexes were trans configuration with five-membered ring hydrogen bonds, and the infrared absorption was more obvious.V O (OE) was related to the polarities of the substituents of the complex.The MO, MN Key infrared characteristic frequency of 2-hydroxy-5-octylbenzophenone oxime and 2-hydroxy-4-octyloxybenzophenone oxime with ~ (63) Cu and ~ (65) Cu IR Spectral Isotopic Displacement of Complexes.
