A heterotrinuclear and a polynuclear complex constructed from a ferrocenyl carboxylate and an N-containing ligand: Synthesis, crystal structures and electrochemical properties

A heterotrinuclear and a polynuclear complex constructed from a ferrocenyl carboxylate and an N-containing ligand: synthesis, crystal structures and electrochemical properties. Two novel ferrocene-containing complexes have been prepared and structurally characterized. In heterotrinuclear complex 1, two Cd atoms and one Fe atom are bridged by μ-coordinated, μ2-coordinated or tridentate −O2CHC(Me)Fc anions forming a Cd-Fe-Cd unit. In complex 2, the pbbm ligands connect Cd atoms leading to a one-dimensional chain [Cd(pbbm)]n with −O2CC6H4{C(O)Fc-o} ligands acting as chelating ligands in the side chain. The electrochemical properties of the two complexes were determined.
