Phosphaferrocenes in combination with coinage metal salts proved to be excellent building blocks in supramolecular chemistry for the buildup of oligomeric and polymeric assemblies. The synthesis of a series of novel phosphaferrocenes containing the 1,3‐P 2 C 3 i Pr 3 and/or the 1,2,4‐P 3 C 2 i Pr 2 ligand is described herein. The self‐assembly processes of the 1,3‐diphospha‐, 1,2,4‐triphospha‐, and 1,1′,2,3′,4‐pentaphosphaferrocenes with Cu I halides led to the formation of 1D or 2D polymers. With [Cp*Fe(η 5 ‐P 2 C 3 i Pr 3 )] (Cp* = η 5 ‐C 5 Me 5 ), infinite chains are formed, whereas with [(η 5 ‐P 3 C 2 i Pr 2 )Fe(η 5 ‐P 2 C 3 i Pr 3 )] 1D ladderlike structures are obtained. These are the first polymers containing such a di‐ and pentaphosphaferrocene, respectively. On the other hand, the use of [Cp*Fe(η 5 ‐P 3 C 2 i Pr 2 )] leads to the construction of 2D networks with intact sandwich complexes, which is uncommon for this class of complexes.
