摘要
合成了新的十一个2-(N-十六烷基氨基甲酰基)-8-羟基喹啉(C26H39N2O2,简写为HL)的配合物[ML2],(M=Mn(Ⅱ)、Co(Ⅱ)、Ni(Ⅱ)、Zn(Ⅱ)、Cd(Ⅱ)、Pd(Ⅱ)、Mg(Ⅱ)和Ca(Ⅱ))、[ML2Cl(H2O)4](M=La(Ⅲ)、Ga(Ⅲ))和[CuLCl],并经元素分析、摩尔电导、磁性和红外光谱所表征。红外光谱表明:配合物是以三齿形式与金属离子配位。配合物中C-O键伸缩振动频率与中心金属离子的相对原子质量或中心离子的电离势呈双线性关系。
Eleven new complexes of 2 (N hexadecylcarbamoyl) 8 hydroxyquinoline (HL)were synthesized and characterized by elemental analyses, conductivity measurement and room temperature magnetic moment. Their infrared spectra were carefully studied. In the infrared spectra of the complexes, a strong preak at about 1100 cm -1 is assigned to the characteristic of the C-O vibration in C-O-M bond of the complexes. When the positions of these peaks are plotted against the atomic weight or the ionization potential of the corresponding metals, the points appear to fall into two groups. It is suggested that this may indicate a difference in M O and M N bonding for the two classes of complexes.
