| Abstract: | Vanadium(V) oxoazide VO(N3)3] was prepared through a fluoride–azide exchange reaction between VOF3] and Me3SiN3 in acetonitrile solution. When the highly impact‐ and friction‐sensitive compound VO(N3)3] was reacted with 2,2′‐bipyridine, the adduct (bipy)VO(N3)3] was isolated. The reaction of VO(N3)3] with PPh4]N3 resulted in the formation and isolation of the salt PPh4]2VO(N3)5]. The adduct (bipy)VO(N3)3] and the salt PPh4]23VO(N3)5] were characterized by vibrational spectroscopy and single‐crystal X‐ray structure determination, making these compounds the first structurally characterized vanadium(V) azides. |
