Reinvestigation of hydrazinium tetrafluoroborate

M. Kowalewski, P. Mayer, A. Schulz and V. Villinger

Abstract: The single-crystal X-ray study of hydrazinium tetrafluoroborate, N₂H₅⁺·BF₄^-, confirms the previous structure determinations in the space group C2/c [Conant, Corrigan & Sparks (1964). Acta Cryst. 17, 1085; Conant & Roof (1970). Acta Cryst. B26, 1928-1932]. The present study includes the determination of the H-atom parameters, which reveal an extensively hydrogen-bonded structure, as expected. Several interionic hydrogen bonds are found, involving short NF distances [2.929 (3)-2.989 (3) Å] and a short NN distance [2.916 (3) Å].
