The First Coordination Polymers Based on 1,3-Diphosphaferrocenes and 1,1',2,3',4-Pentaphosphaferrocenes.

ABSTRACT: 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-P₂C₃iPr₃ and/or the 1,2,4-P₃C₂iPr₂ 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(η⁵-P₂C₃iPr₃)] (Cp* = η⁵-C₅Me₅), infinite chains are formed, whereas with [(η⁵-P₃C₂iPr₂)Fe(η⁵-P₂C₃iPr₃)] 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(η⁵-P₃C₂iPr₂)] leads to the construction of 2D networks with intact sandwich complexes, which is uncommon for this class of complexes.
