Trichlorobis[2,6-di(phenylamino)pyridinato-N,N']tantalum(V) Toluene Solvate (1/1)

The title compound, [TaCl3(C17H14N3)(2)].C7H8, is formed when 2,6-bis(phenylamino)pyridine and tantalum(V) chloride are refluxed in toluene. The organic ligand loses an amino proton and forms a sigma bond with the metal atom, while its pyridine N atom acts as a donor. A small chelate ring is thus formed. The two bidentate ligands the three Cl atoms afford a seven-coordinate central atom.
