A criterion from vibrational spectra for distinguishing the N2H+5 from the N2H2+6 ion: vibrational spectra of hydrazinium (1+) and (2+) fluorometalates and Raman spectra of hydrazinium (1+) and (2+) fluorides in the 900–1700 cm−1 region

The sole dependable criterion is the activity of this vibration which appears in N,Hi+ compounds only in the Raman and in N,Hl compounds both in the Raman and the i.r. independent of ion conformation. Multiple N-H deformation and rocking absorptions reflect solid state interactions in fluorometalate
