胡椒醛缩异烟肼与钴、镍、铜和镉配合物的合成和表征

SYNTHESIS AND CHARACTERIZATION OF THE COMPLEXES OF COB ALT, NICKEL, COPPER AND CADMIUM WITH PIPERONAL ISONICTINOYL HYDRAZONE

合成了以胡椒醛缩异烟肼（HPIN）为配体的四个新配合物:M（PIN）2·nH2O[M=Co（Ⅱ）、Ni（Ⅱ）、Cu（Ⅱ）和Cd（Ⅱ）,n=0.5～4]。通过元素分析、红外光谱、摩尔电导、紫外可见光谱、磁化率测定、1H核磁共振谱和差热分析等研究了配合物的组成和性质。

The synthesis and characterization of cobalt (II), nickel (II), copper (II) and cadmium(II) complexes with piperonal isonicotinoyl hydrazone(HPIN)are reported. Elemental analysis,molar conductance, magnetic measurements,electronic and I. R. spectra,and differential thermal analysis studies have been used to characterize the complezes. The analytical data show that the 1 : 2 complexes are M(PIN)2nH2O[M=Co(lI) ,Ni(lI) ,Cu(Il). or Cd(Il) ,n=0. 5- 4]. A four coodinate geometry has been proposed for these complexes on the basis of magnetic and spectral measurements.
