Characterization of the S2N2H– ion by 14N and 15N NMR spectroscopy
Abstract
14 N and 15N NMR spectroscopy shows that the deprotonation of S7NH by potassium amide in liquid ammonia proceeds via the sequential formation of S7N–, S4N–, and S3N– to give S2N2H–, which subsequently decomposes to S3N3–; the S2N2H– ion is also produced by treatment of S4N4H4 with 2 mol equiv. of potassium amide in liquid ammonia.
