Synthesis, structure and physical properties of an iron(II) complex with four ferrocenyl groups

A novel tridentate ligand with two ferrocenyl groups and its iron(II) complex were synthesized and these structures and physical properties are presented. The pentanuclear iron(II) complex is composed of one central ion(II) ion and four ferrocenyl groups, in which the central iron(II) ion was coordinated by two tridentate ligands. Electrochemical measurement for the complex in MeCN showed irreversible redox waves, and the redox process can be understood by EC mechanism.
