The glycinium compounds glycine glycinium tetrafluoroborate (GlyH_Gly_BF4) (I), glycine glycinium perchlorate(GlyH_Gly_ClO4) (II), glycinium tetrafluoroborate (GlyH_BF4) (III), glycinium perchlorate (GlyH_-ClO4) (IV), and glycine glycinium iodide (GlyH_Gly_I) (V) have been synthesized, (I-IV) for the firsttime. The crystal structures could be determined for (I), (II), and (V), the first two represent novel speciesand have therefore been characterized by vibrational spectroscopy as well. Compounds (III) and (IV)proved unstable and are characterized by vibrational spectroscopy only. The results of the redeterminationof (V) are compared with previously reported data. The crystal structures comprise dimeric cations ofthe type (GlyH...Gly) connected to monovalent anions via hydrogen bonds.
