Across the Dimensions: A Three-Component Self-Assembly of Pentaphosphaferrocene-based Coordination Polymers.

Pentaphosphaferrocenes [Cp Fe(η -P )] (Cp*=η -C Me ) (A), Cp''=η -C H tBu -1,3 (B)) are excellent building blocks for polymeric assemblies in supramolecular chemistry in combination with coinage metal salts of weakly coordinating anions such as AgSbF . Adding rigid aromatic dinitriles ortho/meta/para-(NC) C H in a one-pot reaction between [Cp Fe(η -P )] and AgSbF leads to various coordination polymers (CPs) by a three-component self-assembly. The sterical demand of the differently substituted cyclopentadiene ligands as well as the rigid constitution of the isomeric dinitriles (NC) C H play a key role in the formation of the isolated CPs. All CPs were characterized by NMR spectroscopy, mass spectrometry, elemental analysis, and single-crystal X-ray diffraction.
