    Abstract:
    Protonated form of hypoxanthinium chloride monohydrate single crystal has been grown from dilute hydrochloric acid. Single crystal X-ray analysis was carried out and the titled crystal belong to the monoclinic P2(1)/c space group. Hypoxanthine is protonated at N(1) with the hypoxanthine cations, linked to chlorine anion via weak bifurcated N-H...Cl hydrogen bonds and interconnected by hydrogen bonding contacts of the type N-H...O. Infrared, Raman and UV spectroscopic tools were applied to characterize hypoxanthinium chloride monohydrate. By applying group theoretical methods the internal and external modes of vibrations of the title crystal have been identified and discussed.
