Crystal Structure of Hydrazinium Iodide by Neutron Diffraction


The structure of hydrazinium iodide, [H5N2]+·I, at 100 K has monoclinic (P21/n) symmetry from single crystal neutron diffraction with a = 7.4599(7) Å, b = 5.3185(6) Å, c = 10.1628(11) Å, β = 103.150(10)°, V = 392.64(7) Å3, Z = 4. The refinement converged to R = 0.0575, wR 2 = 0.1602, S = 1.022. Data for the crystal structure was collected on the SNS TOPAZ single-crystal time-of-flight Laue diffractometer. The compound has a one-dimensional structure which displays N–H···N hydrogen bonding. Accurate intra- and intermolecular N–H distances have been determined.
