2-(2-Pyridylamino)pyridinium Salts of closo-Hydridoborate Anions BnHn2- (n = 6,10, or 12)
2-(2-Pyridylamino)pyridinium salts (Hpy2NH)2B12H12, (Hpy2NH)2B10H10 – 2H2O, and (Hpy2NH)2B6H6 – 2H2O were synthesized and then characterized by IR spectroscopy. On the basis of IR spectroscopic data, the behavior of imino groups of 2-(2-pyridylamino)pyridinium in the title compounds is considered. X-ray structural analysis of the (Hpy2NH)2B10H10 – 2H2O is performed. The crystals are triclinic, a = 9.649(2) A, b = 10.020(1) A, c = 14.924 A, alpha = 93.23(2), beta = 98.44(2), gamma = 106.45(1), V = 1361.6(6) A3, space group P 1? (no. 2), Z = 2.
