Properties: Orthorhombic crystals. mp 99.6-99.7°; bp 213°; bp19 100°. d425 0.94; d4100 (liq) 0.78. Stable indefinitely at room temp; decomp slowly into B + H2 at 300°. Heat of fusion: 7.8 kcal/mole; of sublimation: 18.33 kcal/mole; of vaporization: 11.6 kcal/mole. Slightly sol in cold water; hydrolyzes in hot water. Sol in ethyl acetate, 1-bromopropane, ethyl silicate, carbon disulfide, benzene, alcohol, acetic anhydride, acetic acid, ethyl borate, carbon tetrachloride. Highly reactive. Reacts with amides, acetone, butyraldehyde, acetonitrile at room temp. Decaborane mixtures with carbon tetrachloride are dangerously shock sensitive.
