Abstract

original image

Shock-sensitive and highly explosive V(N3)4 was prepared from VF4 and Me3SiN3 by fluoride–azide exchange. Salts of the [V(N3)6]2− anion (see picture) were obtained by treatment of the neutral tetraazide with ionic azides. Vanadium(V) azide, the only binary vanadium(V) compound known apart from VF5, VF6, and V2O5, was successfully prepared from the VF6 anion.
