Abstract:

Boron trifluoride and anhydrous hydrazine react rapidly at 25 C in vacuo yielding a 11 complex compound, BF3.N2H4, while at higher temperatures, or with diethyl ether as solvent, they form complex mixtures containing 52.2 to 63.5 mole percent BF3 but in tetrahydrofuran solution the 21 adduct, 2BF3.N2H4 is formed. The X-ray powder diffraction pattern of BF3.N2H4 consists of 28 lines from which a unit cell with triclinic symmetry was calculated. The thermal decomposition of BF3.N2H4 is complex, yielding in part N2, NH3, NH4BF4, and BN. Hydrolysis of BF3.N2H4 yields a mixture of hydroxyfluoroborate ions. At -80 C, BF3.N2H4 absorbs NH3 to form a diammoniate which liberates NH3 slowly at higher temperatures. Partial displacement of BF3 from BF3.N2H4 by HCl and partial absorption of HCl by BF3.N2H4 occur simultaneously at 110 C. Author
