Ferrocene-Containing Coordination Polymers: Ligand Design and Assembled Structures

This review describes the preparation and structures of ferrocene-containing coordination polymers with a focus on ligand design. Neutral ligands such as heteroaryl ferrocenes and anionic ligands such as ferrocenyl carboxylates can be used to construct one-dimensional coordination polymers of various structural types. The main-chain and side-chain polymer structures are designed, and the conformational flexibility of ferrocenes leads to structural variety. The use of additional bridging ligands along with the anionic ligands leads to extended one-to three-dimensional structures. These complexes exhibit various properties, including characteristic redox activities.
