The results of laboratory measurements are reported for the reactions of Cl2O with NO2(1-)*(D2O)_n=0-2, NO3(1-)*(D2O)_n=0-2, and Cl(1-)*(D2O)_n=0-2.These were studied using a flow-tube apparatus at several temperatures within the range 168-298 K and at a helium buffer gas pressure of 0.30+/-0.02 Torr.Rate constants for primary reactions and product ions observed in various reaction sequences are reported, along with a discussion of possible reaction mechanisms.The findings contribute to a further mechanistic understanding of ionic reactions as well as other heterogeneous ones involving chlorine-containing molecules.Interestingly, evidence for a water-catalyzed reaction between Cl2O and Cl(1-)/NO3(1-) was obtained.Also, the present findings suggest that several ionic reactions may lead to the formation of ClONO2 as a neutral product.Finally, limits on the electron affinity of Cl2O are determined to be 2.52 eV <*> EA(Cl2O) <*> 3.61 eV.
