| Abstract: | The synthesis and physical properties of meta- and para-bis(metallocene) benzene complexes with M = Fe, Co, Ni are reported. The electrochemical properties suggest greater electronic interaction between metal centers in the para-M complexes. In addition, the magnetic properties suggest different degrees of spin exchange for the meta and para complexes, with the latter exhibiting more pronounced antiferromagnetic coupling. These molecular complexes are considered prototypes for extended metallocene polymers. |
