摘要
用两种N-取代四氮杂大环四乙酸配体分别与硝酸铀酰和硝酸钍反应得到固体配合物。经元素分析确定配合物的组成分别为(UO_2)_2L·nH_2O,Th_2L(NO_3)_4·nH_2O。通过X射线粉末衍射、红外光谱、差热热重谱、摩尔电导等测定,研究了配合物的有关性质。
The synthesis and characterization of the following two new N-functiona-lized tetraazamacrocycles :5, 7, 12, 14-tetramethyl-1, 4, 8, 11-tetraazamacro-cyclotetradecane-N' ,N' ,N'' ,N''-tetraacetic acid(H4L1) ;5 ,12-diphenyl-7, 4-dimethyl-1 ,4,8, 11-tetraazacyclotetradecane-N' ,N' , N'', N''-tetraacetic acid (H4L2) and their uranyl and thorium complexes are reported.The complexes in microcrystalline powder have constant stoichiometry (UO2)2L·nH3O and Th2 L·(NO3)4·nH2O, irrespective of the metal to ligand ratio used in the preparation All these compounds are characterized by elemental analysis,X-ray powder diffraction, thermoanalysis, conductivity measurement, NMR and IR spectra.
