水杨酸镍配合物的合成和红外光谱研究

Studies on Synthesis and IR Spectrum of Nickel Salicylates Complexes

用流变相反应法合成了 3个水杨酸镍配合物。通过元素分析、TG确定了这些配合物的组成 ,并对40 0 0～ 40 0cm-1的主要红外光谱吸收峰进行了归属 ;红外光谱表明一水杨酸镍的羟基吸收峰明显地向高波数方向移动 ,证明其中有氢氧根存在。

Nickel salicylates complexes were synthesized wi th the rheologic phase reaction method.The composition of these complexes were c onfirmed by elemental analysis,TG and IR,the principal infrared absorption peaks were assigned for the region 4 000—400 cm- -1.The IR spectra indic ated that a hydroxyl group on Ni atom was occured and so absorption peaks of hyd roxyl group were shifted obviously to higher frequency in nickel monosalicylates .
