在无水乙醇中制备了磺胺醋酰与镧、镨、钕、钐、铕和钆六种固态化合物。元素分析它们的组成为 NaLn(SA)_4·4H_2O(SA 为磺胺醋酰,Ln为镧、镨、钕、钐、铕和钇)。测定了化合物的溶解性和在无水乙醇,无水二甲基甲酰胺中的摩尔电导。从红外和紫外光谱推测,化合物的分子结构中含有O、O′配位螯合的络阴离子。对化合物作了X 光粉末衍射相分析和测定了热稳定性。
Sulfanilamide and six solid compounds of lanthanum, praseodymium, neodymium, samarium, europium and gadolinium were prepared in anhydrous ethanol. Elemental analysis of their composition NaLn (SA) _4 · 4H_2O (SA is sulfanilamide, Ln lanthanum, praseodymium, neodymium, samarium, europium and yttrium). The compound’s solubility and molar conductance in absolute ethanol, anhydrous dimethylformamide were determined. From the infrared and ultraviolet spectra speculated that the molecular structure of compounds containing O, O ’coordination chelate complex anion. X-ray powder diffraction phase analysis and thermal stability of the compounds were determined.
