Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>The reaction of [Cp^BnFe(η⁵‐P₅)] (<bold>1</bold>) (Cp^Bn=η⁵‐C₅(CH₂Ph)₅) with CuI selectively yields a novel spherical supramolecule (CH₂Cl₂)_3.4@[(Cp^BnFeP₅)₁₂{CuI}₅₄(MeCN)_1.46] (<bold>2</bold>) showing a linkage of the scaffold atoms which is beyond the Fullerene topology. Its extended CuI framework reveals an outer diameter of 3.7 nm—a size that has not been reached before using five‐fold symmetric building blocks. Furthermore, <bold>2</bold> shows a remarkable solubility in CH₂Cl₂, and NMR spectroscopy reveals that the scaffold of the supramolecule remains intact in solution. In addition, a novel 2D polymer [{Cp^BnFe(η⁵‐P₅)}₂{Cu₆(μ‐I)₂(μ₃‐I)₄}]_{<italic>n</italic>} (<bold>3</bold>) with an uncommon structural motif was isolated. Its formation can be avoided by using a large excess of CuI in the reaction with <bold>1</bold>.</p> </abstract>
