## Abstract A new Schiff base of gossypol with 3,6,9βtrioxaβdecylamine (GSTB) forms stable complexes with monovalent cations. This process of complex formation was studied by electrospray ionization mass spectrometry, ^1^HβNMR and FTIR spectroscopy, and the PM5 (parametric method 5) semiempirical m
1 Ε½ . H spin-lattice relaxation times and second moments were determined for polycrystalline CH NH Sb Br sample in a 3 3 3 2 9 Ε½ . 2 Ε½ . wide range of temperature 5-200 K at 24.6 and 55.2 MHz. H NMR spectra of CD NH Sb Br were recorded between 3 3 3 2 9 5 K and room temperature. The relaxation time
