Cage Metal Complexes: Synthesis, X-ray Structure, and Spectral and Redox Behavior of the First Hybrid Iron(II) Clathrochelatoscorpionate and Its Pyrazoloxime-Armed Macrocyclic Intermediate



Cycloaddition of a new pyrazoloxime to macrocyclic iron(II) bis(α-benzyldioximate) unexpectedly gave a mixture of the first hybrid clathrochelatoscorpionate and its pyrazoloxime-armed macrocyclic intermediate, which were characterized by X-ray crystallography, spectroscopy, and cyclic voltammetry.
