Abstract

The presence of directed localized cation–anion interactions in the semihydrate of 2,4,6-triamino-1,3,5-triazine (melamine) dodecahydro-closo-dodecaborate (С₃Н₆N₆Н)₂В₁₂Н₁₂ · 0.5Н₂О is discovered by means of IR and NMR-spectroscopy (¹¹В, ¹Н, С, N). The hypothesis that melamine protonation proceeds on the ring atom of nitrogen is confirmed via quantum-chemical calculations.
