ABSTRACT. Inclusion complex between 3-amino-1,2,4-triazole picrate and β-cyclodextrin was synthesized in order to increase the solubility. The obtained by co-precipitation method its stoichiometry is 1:1 (guest–host). structure of has been established UV, X-ray diffractometry powder spectra, TGA, DSC, IR, 1H NMR, 13C NMR. influence effect pH on complexation discussed. value apparent formation c...
