The Fourier transform IR and Raman spectra of (C 6 H 16 N 4 O 2 2+ ·2NO 3 − ) crystal were studied and the observed IR and Raman lines were assigned. There is extensive intermolecular hydrogen bonding in the crystal and this is responsible for the changes in the position and intensity of several bands. The vibrational spectra show that the carboxyl group forms a strong hydrogen bond whereas the nitrogen atoms of the amino and guanidyl groups of the cation form normal hydrogen bonds with the oxygen atoms of the anions.
