Some Mixed Ligand Complexes of Tungsten Oxytetrachloride

Abstract

Some mixed ligand derivatives of WOCl₄ have been synthesized and characterized by their elemental analysis, IR and electronic spectra. The amide ligands are attached to tungsten atom within coordination sphere providing an octahedral geometry to the complex
molecule. The amide ligand is removable by simple heating.
The tungsten atom-phenoxy linkage is slowly ruptured by boiling
in alcohol. This particular property has been utilised for the synthesis
of mixed phenoxy complexes without amide ligands but with
cyclopentadienide and indenide groups—a new way of synthesis of
mixed phenoxy complexes containing π-bonded cyclopentadienyl
and indenyl groups.
