Polyazide Chemistry: Preparation and Characterization of As(N₃)₅, Sb(N₃)₅, and [P(C₆H₅)₄][Sb(N₃)₆]

Abstract

After all, neat As(N3)5 can be isolated: By analogy with AsCl5, neat As(N3)5 was predicted to be a highly unstable compound, and previous attempts at its synthesis had resulted in intense explosions. The successful syntheses and characterization of neat As(N3)5 and Sb(N3)5 and the crystal structure of the [Sb(N3)6]− ion (see picture) are now described.
