Metal-Deficient Supramolecule Based on a Fivefold-Symmetric Building Block.

ABSTRACT: An unprecedented cationic supramolecule [(Cp''Fe(η⁵ -P₅ ))₁₂ {CuNCMe}₈ ]⁸⁺ 2.66 nm in diameter was selectively isolated as a salt of the weakly coordinating anion [Al{OC(CF₃ )₃ }₄ ]^- for the first time and characterized by X-ray structure analysis, PXRD, NMR spectroscopy, and mass spectrometry. Its metal-deficient core contains the lowest possible number of Cu atoms to connect 12 pentaphosphaferrocene units, providing a supramolecule with fullerene topology which, topologically, also represents the simplest homologue in the family of metal-deficient pentaphosphaferrocene-based supramolecules [{Cp^R Fe(η⁵ -P₅ )}₁₂ (CuX)_20-n ].
