Spectrochemistry of solutions. Part 12. Cyano-complexes of silver(I) in solution in liquid ammonia
Abstract
Raman spectra of cyano-complexes of silver(I) in liquid ammonia solution have been interpreted to show the existence, in equilibrium, of the following species: AgCN, AgNC, [Ag(CN)2]–, [Ag(CN)(NC)]–, [Ag(NC)2]–, [Ag(CN)3]2–, [Ag2(CN)]+, [Ag2(CN)2], [Ag2(CN)3]–, [MAg2(CN)5]2–(M = Na+ or K+), and [MAg(CN)3]–(M = Li+, Na+, or K+). The factors affecting the linkage isomerism, ion aggregation, ion pairing, and silver complexation are discussed.
