Polyazide Chemistry: Preparation and Characterization of As(N3)5, Sb(N 3)5, and
6H5)4][Sb(N3)6]. — As revealed by single crystal XRD, (IVb) crystallizes in the
10- 021 [P(C
monoclinic space group C2/c with Z = 4. The structure contains [PPh4]+ and [Sb(N3)6]ions without significant cation—anion interaction. The structure of the [Sb(N3)6]- ion
is only slightly distorted from ideal S6 symmetry and consists of an asymmetric SbN 9
unit with three azido groups covalently bonded in a trigonal pyramidal fashion to the
Sb center. The remaining three coordination sites are occupied by three symmetry
related azido groups. The compounds (III) and (IV) are further characterized by Raman
spectroscopy. — (HAIGES*, R.; BOATZ, J. A.; VIJ, A.; VIJ, V.; GERKEN, M.;
