Abstract
The crystal structure of hydrazinium(2+) aquatetrafluoroindate(III), N2H6(InF4H2O)2, has been determined by X-ray diffraction. The compound crystallizes in the triclinic space group \(P\bar 1\) (C i 1) with a = 6.759(2) Å, b = 6.228(1) Å, c = 5.7854(7) Å, α = 80.28(2)°, β = 88.79(1)°, γ = 69.96(2)°, V = 225.3(1) Å3, and Z = 1. The structure comprises hydrazinium(2+) cations and InF2F4/2O− anions in which In appears to be seven-coordinated in the form of a pentagonal bipyramid by four bridging fluorine atoms, two terminal fluorine atoms, and one oxygen atom. Pentagonal bipyramids are interconnected and form chains along a axis. Bands in vibrational spectra were assigned to the vibrations in N2H6 2+ cations and anionic InF2F4/2O− entities. The rather intensive band appearing at 1042 cm−1 in Raman spectrum, which is absent from infrared, is characteristic of the N2H6 2+ cation, in line with the predictions of the unit-cell group analysis for the studied system.
