By means of chemical and X-ray phase analysis, IR spectroscopy, differential scanning calorimetry, thermogravimetry interaction of dodecahydro-closo-dodecaboric acid with 2,4,6-triamino-1,3,5-triazine (melamine) and the resulting insoluble (С3Н6N6Н)2В12Н12 were studied. According to the IR studies, there is a noticeable cation-anion interaction in it, while the accession of the proton occurs to nitrogen of the amino group. It was established that its decomposition starts at 290 °С. Above 320 °C, a pumice-like product of yellow color is formed, presumably containing graphite-like carbon nitride β-С3N4. Upon contact of (С3Н6N6Н)2В12Н12 with the hot surface or when ignited it flashes a bright white flame with the emission of light ash that can be considered as a promising heat-resistant energy-rich compound.
