The binary selenium(IV) azides Se(N3)4, [Se(N 3)5]-, and [Se(N3)6] 2-

Abstract

(Figure Presented) Black, red, gold: The reaction of SeF4 with Me3SiN3 at low temperatures results in the formation of the first binary selenium(IV) azide Se(N3)4. The decomposition in an NMR tube shows the colors of gray selenium, red selenium, and the desired yellow selenium tetraazide (see picture). The reactions of [SeF5]- and [SeF6]2- with Me 3SiN3 furnish the corresponding polyazidoselenites [Se(N3)5]- and [Se(N3) 6]2-. All materials are extremely temperature-sensitive. © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
