摘要：

The crystal structure of lanthanum 4-amino-benzenesulfonate complex has been determined by X-ray diffraction. The crystal data indicate that lanthanum and neodymium 3-amino-benzenesulfonates are isomorphous. The FT-IR spectroscopic study of rare earth 4-amino-benzenesulfonare complexes showed that the spectra of light rare earth (La, Nd, Sm, Eu) complexes are similar and so are the spectra of heavy rare earth (Dy, Er, Y) complexes. There are remarkable differences between the spectra of light rare earth and heavy rare earth complexes. Based on above results, we infer that light rare earth (La, Nd, Sm, Eu) complexes are isomorphous and three heavy rare earth (Dy, Er, Y) complexes are of a different structure but also isomorphous.
