The preparation, characterization in solution of the 7π radical 1,2,4-triseleno-3,5-diazolylium and the 6π(1,2,4-triseleno-3,5-diazolium)2+ cations, and the X-ray crystal structures of (SeNSeNSe)2(AsF6)2 and SeNSeNSe(AsF6)2 containing the first stable binary selenium–nitrogen species

Abstract

([graphic omitted])n(AsF6)2(n= 1,2) containing the first stable binary selenium–nitrogen species, have been prepared by the reaction of stoicheiometric quantities of Se4(AsF6)2(n= 2) or AsF5(n= 1 and 2) with Se4N4 in liquid SO2, and their structures determined by X-ray crystallography; in solution ([graphic omitted]e)2(AsF6)2 gives the indefinitely stable 7π radical [graphic omitted]e+˙(e.s.r. spectrum of frozen powder), and [graphic omitted](AsF6)2 the 6π [graphic omitted]e2+(Raman and 14N n.m.r. spectra).
