Green [HIPTN₃N]V(THF) ([HIPTN₃N]^3- = [(HIPTNCH₂CH₂)₃N]^3-, where HIPT = 3,5-(2,4,6-i-Pr₃C₆H₂)₂C₆H₃) canbe prepared in a 70-80% yield via the addition of H₃[HIPTN₃N] to VCl₃(THF)₃ in THF, followed by the addition ofLiN(SiMe₃)₂. From [HIPTN₃N]V(THF), the following have been prepared: {[HIPTN₃N]VN₂}K, [HIPTN₃N]V(NH₃),[HIPTN₃N]V=NH, [HIPTN₃N]V=NSiMe₃, [HIPTN₃N]V=O, [HIPTN₃N]V=S, and [HIPTN₃N]V(CO). No ammonia isformed from dinitrogen using {[HIPTN₃N]VN₂}K, [HIPTN₃N]V=NH, or [HIPTN₃N]V(NH₃) as the initial species underconditions that were successful in the analogous [HIPTN₃N]Mo system. X-ray structural studies are reported for[HIPTN₃N]V(THF) and [HIPTN₃N]V(NH₃).
