    Three novel inorganic salts of aniline with sulfuric and selenic acids were prepared and characterized by X-ray structural analysis. Anilinium(1+) selenate, (C(6)H(5)NH(3)(+))(2)SeO(4)(2-), and anilinium sulfate, (C(6)H(5)NH(3)(+))(2)SO(4)(2-), crystallize in the monoclinic space group C2. The crystal structures are based on hydrogen bonded layers of alternating anilinium cations and inorganic anions. Anilinium( 1+) selenate dihydrate, (C(6)H(5)NH(3)(+))(2)SeO(4)(2-)center dot 2H(2)O, crystallizes in the monoclinic space group C2/c. The crystal structure is formed by a network of alternating anilinium cations, selenate anions and water molecules connected by a system of intermolecular hydrogen bonds. The FTIR and Raman spectra of all the compounds have been recorded and discussed as well as their crystal structures. According to the DSC curves and temperature dependence of lattice parameters, anilinium sulfate exhibits phase transitions at 217 and 182 K.
