Abstract:
The reaction of the oxidovanadium(V) complexes with N,N-dimethylhydrazine was demonstrated to afford the corresponding vanadium(V) dimethylhydrazido complexes. The substituent at the 3-position of the tris(2-hydroxyphenyl)amine ligand was found to influence the electronic environment of the vanadium center. The crystal structure of the non-substituted vanadium(V) dimethylhydrazido complex exhibited a distorted trigonal bipyramidal geometry with phenolate oxygen atoms in equatorial positions and the near-linear V(1)-N(2)-N(3) angle. The vanadium(V) diphenylhydrazido complexes could be obtained by the reaction of the oxidovanadium(V) complexes with N,N-diphenylhydrazine. A distorted trigonal bipyramidal geometry with phenolate oxygen atoms in equatorial positions was also observed in the crystal structure of the non-substituted vanadium(V) diphenylhydrazido complex.

1° Amines to Diazonium or Aryldiazonium Salts: Diazotization with NaNO2 Overview
The nitrous acid is unstable. Hence, it is formed in situ from a solution of sodium nitrite and cold aqueous acids such as hydrochloric or sulfuric acid. In an acidic solution, the –OH group of nitrous acid undergoes protonation to give oxonium ion, followed by water loss...
