Abstract
The Raman spectra of sodium and potassium salts of [NO3]–, [NO2]–, [NCO]–, [NCS]–, [N3]–, and [CN]– in liquid ammonia in the presence of an equimolar amount of the cryptand C222 show a set of single bands characteristic of the free solvated anion. The presence of the ether benzo-15-crown–5 had comparatively little effect on the spectra of sodium and potassium cyanides, which displayed bands characteristic of ion-associated species. The effects of cation-complexing agents on ion association in liquid-ammonia solutions are briefly discussed.Keywords
