Abstract
A donor-acceptor interaction between H+-cations of dodecahydro-closo-dodecaboric acid and the amine group of chitosan results in the generation of chitosanium dodecahydro-closo-dodecaborate, (C6O4H9NH3)2B12H12 — water-insoluble salt. The presence of four pairs of donor oxygen atoms in its composition makes for the existence of (C6O4H9NH3)2B12H12× nH2B12H12 (0 < n ≤ 4) compounds. When treating the latter with gaseos ammonia, the compounds of (C6O4H9NH3)2B12H12×n(NH4)2B12H12 (0 < n ≤ 4) composition are formed. The individuality of the compounds was confirmed by IR and X-ray PE spectral studies, chemical and X-ray phase analyses, and thermogravimetry.
