Article abstract of DOI:10.1107/S0108270196011328

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 σ 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 and three Cl atoms afford a seven-coordinate central atom.
