镧(Ⅲ)与硫脲配合物的合成、表征及抗菌活性研究

Synthesis,Characterisation and Antibacterial Activity Complex of La(Ⅲ)with Thiourea

本文报道了配合物LaI3.2CS(NH2)2.10H2O的合成方法,通过元素分析、X射线粉末衍射、红外光谱、核磁共振谱、质谱、差热——热重分析,确定了配合物的组成和结构,首次测定了配体和配合物的抗菌活性。

In this psper,the complex LaI3·2CS（NH2）2·10H2Ohas been synthesized with a new synthesis method.The complex composition was determined by elemental analysis.The complex has been characterixed by methods of X—ray powder diffraction,infrared analysis,nuclar nagnetic resonance spectra,mass spectra,and thermogravimetry and differential thermal analysis.And the antibacterial activity of the complex.thiourea,and lanthanum iodide is studied firstly.
