摘　　要：The interactions of nine rare earth perchlorate complexes with alanine and imidazole were studied in methanol. The general formulae of these compounds are RE(Ala) 2Im(ClO 4) 3· n H 2O(RE=Ce, Pr, Nd, Sm, Eu, Gd, Tb, Yb) and La(Ala) 3Im(ClO 4) 3·H 2O, respectively. The composition and structure of the prepared compounds were determined by the chemical analysis, elemental analysis, IR spectroscopy, UV, FS spectroscopy, X ray powder diffraction, 1H NMR and solubility. The thermal decomposition processes of these complexes were studied on the basis of TG DTG. The preliminary bioassay shows that the compounds have a remarkable bacteriostasis effect on nine varieties of microbe.The interactions of nine rare earth perchlorate complexes with alanine and imidazole were studied in methanol.
