First structural characterization of neutral, base-stabilized group 15-pentaazides: single crystal X-ray structures of dmap-As(N3)5 and dmap-Sb(N3)5.

Two neutral group 15-pentaazides dmap-As(N(3))(5) (1) and dmap-Sb(N(3))(5) (2) were synthesized and structurally characterized for the first time (dmap = 4-dimethylaminopyridine). Base-stabilization was confirmed to be very suitable for the kinetic stabilization of highly explosive covalent main group polyazides.
