摘要

The complexes [W(X)Cl₃(HO₂CC₆H₄NH-2)] [X=O (1), NPh (2)] have been obtained by reaction of either [WOCl₄] or [W(NPh)Cl₄(Et₂O)] with anthranilic acid {1,2-(NH₂)(CO₂H)C₆H₄}, respectively. The X-ray crystal structures reveal pseudo-octahedral metal centres, each with a mer-arrangement of chlorines and a chelating acid/amide ligand derived from anthranilic acid. The acid group of this chelate ligand is trans to either the oxo or organoimido functionality.
