Two coordination possibilities for the phenylisocyanate ligand are realized in the thio crown ether complex 1 . Crucial are only the stereochemically different environments of the axial positions at the metal center. Such discrimination of the potentially coordinating parts of the polyfunctional phenylisocyanate ligand is also of interest in connection with metal‐induced transformations of isocyanates.
