Synthesis and characterization of hydrazinium azide hydrazinate

Hydrazinium azide hydrazinate, [N2H5]+[N-3](-). N2H4 was synthesized from e quimolar amounts of hydrazinium azide and hydrazine and characterized by si ngle crystal X-ray diffraction: monoclinic, P 2(1/c), a=6.3704(2), b=12.111 1(4), c=6.9940(2) Angstrom, beta = 91.8666(2)degrees, V=539.32(3) Angstrom (3), Z = 4, p = 1,320 g cm(-1). The compound is less hygroscopic and less v olatile than hydrazinium azide. Explosion of [N2H5](+)[N-3](-). N2H4 yielde d dinitrogen (ND, ammonia (NH3) and dihydrogen (H-2). Compared to hydrazini um azide, the hydrazine adduct produces larger amounts of ammonia in the ex plosion.
