The radical ion N2H4+ has been produced by x irradiating single crystals of hydrazinium hydrogen oxalate (N 2H5HC2O4) and studied by ESR and ENDOR spectroscopy. The structure of the trapping site has been elucidated by observing 1H ENDOR transitions not only from the radical but also from distant protons. One of the latter originates from the proton lost by N2H5+ upon radical formation. Evidence that proton transfer occurs through a hydrogen bond is presented.
