The C3N+ ion, generated by electron impact on HC3N and C4N2 and as a product in several ion-molecue reactions, was found to exist in two isomeric forms: CCCN+ and cylic C3N+. These forms were distinguished by their different reactivities with a range of neutral reagents in a selected-ion How tube (SIFT). Isomeric identification was made by reference to existing ab initio calculations. The most reactive isomer, CCCN+, was the major form (≥90%) of the C3N+ ion from all sources of production examined and was found to undergo collision-rate reactions with most of the neutral molecules studied c-C3N+ was much less reactive, which implies an activation barrier in its reactions as it is the higher energy form. Product distributions are reported for the reactions of CCCN+, and rate coefficients for the reactions of both isomers with H2, CH4, NH3, M2O, N2, O2, CO, C2H2, HCN, CO2, and C2N2 at 300 ± 5 K are also given.
