摘要
本文报道胡椒醛缩氨基硫脲(HBTS)与钴(Ⅱ)、镍(Ⅱ),铜(Ⅱ)和镉(Ⅱ)配合物的合成方法,合成了五个新配合物M(BTS)_2·nH_2O[M=Co(Ⅱ)、Ni(Ⅱ)、Cu(Ⅱ)和Cd(Ⅱ);n=0～3]和Cu(BTS)Ac·3H_2O。通过元素分析、红外光谱、紫外可见光谱、摩尔电导、磁矩、~1H核磁共振谱、x一射线粉末衍射和差热分析等表征了配合物的组成和性质。
In this paper the solid complexes of cobalt(Ⅱ) ,nickel(Ⅱ) ,copper(Ⅱ) and cadimum (Ⅱ) with piperonal thiosemicarbazone (HBTS) have been prepared,and their infrared spectra,electronic absorption spectra,molar conductance,magnetic measurement,proton n. m. r. spectra,differential thermal analysis,x-ray powder diffraction and solubility in various solvents have been investigat ed. These are of the type M(BTS)2·nH2O[M=Co(Ⅱ),Ni(Ⅱ),Cu(Ⅱ)or Cd(Ⅱ),n=0-3] and Cu(BTS) Ac. 3H2O. They are soluble in pyridine,dimethylformamide and dimethylsulfoxied ,but insol uble in methanol, ethanol, acetone, chloroform, ethyl ether, benzene, petroleum ether and water. The molar conductance mesurements show their non-electrolytic nature. IR spectral studies reveal that HBTS acts as a mononegative bidentate ligand coordinating through the azomethine nitrogen and the thiono sulphur atoms.
