title: Synthesis of vanadium(V) hydrazido complexes with tris(2-hydroxyphenyl)amine ligands.
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.
