The Raman and infrared absorption spectra of 2(C 5 H 14 N 2 O 2 2+ )·Cl − ·NO 3 − ·SO 4 2− crystal containing three anions were recorded at room temperature and were interpreted in the light of crystal structure data. The presence of a carbonyl group was identified. The carboxylic group was found to exist as COOH. The formation of OH···O, NH···O and NH···Cl asymmetric hydrogen bonds contributes considerably to the crystal cohesion and is responsible for the changes in the position and intensity of several bands. The vibrational spectra show that the anions were found to coordinate through hydrogen bonding interactions to other ligands in the crystal. The lattice wavenumbers of the halide radical (chlorine anion) were also assigned in terms of hydrogen bond vibrations. Copyright © 2004 John Wiley & Sons, Ltd.
