The Ion N2O3+. Binding by One-Electron Transfer


IT has been shown spectroscopically (the evidence will be published shortly1) that the nitrosonium ion in solution forms a molecular compound with nitrogen dioxide: . As the compound may also be produced from nitric oxide and a solution of nitronium ion, one might also consider representing it thus: . Actually, its spectral properties indicate that it has an intermediate constitution, but one which much more closely resembles structure I than II. Thus the high vibration frequency (2,240 cm.−1), depending on the multiple link in the NO-component of the complex, is displaced only one-seventh of the way from the frequency of the nitrosonium ion (2,300 cm.−1) towards the frequency of nitric oxide (1,880 cm.−1).
