Abstract
The reaction of dodecahydro-closo-dodecaboric acid with hexamethylenetetramine (urotropin) was studied by potentiometric titration, chemical and X-ray diffraction analyses, thermogravimetry, and IR and X-ray photoelectron spectroscopy. The donor-acceptor bond with acid H+ cations involves only one of the nitrogen donor atoms of hexamethylenetetramine. The product (C6H12N4H)2B12H12 is isolated as a finely crystalline, easily filterable, and poorly soluble precipitate. A saturated solution of the product contains no more than 0.4 g of the salt per 100 g.
