Raman and infrared line parameters of Zn(NO3)2-H2O systems ranging from dilute solutions (25°C) to ionic liquids of low water content (75°C) are reported. At 25°C the solutions contain a very low concentration of inner sphere [Zn(ONO2)(H2O)5]+, outer sphere [Zn(H2O)6]2+[NO3], Zn(H2O)62+, and NO3 (aq.). In the ionic liquids the ion triplet also exists. Manifestations of a change from the octahedral coordination of zinc to tetrahedral coordination when the water content is very low include the appearance of a 285 cm−1 band from the zinc nitrate bond and a shift to higher frequencies of the band from zinc-water.
