Abstract
Following our studies of cofacial binuclear transition metal complexes, such as $\rm Cu\sb2(XBA)\sb2$ (see below), we became interested in the synthesis of a more rigid ligand, ABIH$\sb2$ which contains a 1,8-anthracene bridge. This new ligand, whose chelating moieties are constrained to be cofacial, should enable us to obtain a wide variety of cofacial bimetallic complexes such as 1, with controllable environments around the metal centers, for synthesis of multi-metal redox active catalysts.(DIAGRAM, TABLE OR GRAPHIC OMITTED...PLEASE SEE DAI). Three routes have been pursued to synthesize the anthracene-based ligand. Using organometallic derivatives of 3,5-dimethylisoxazole as acetylacetone synthons, the bis($\beta$-ketoenamine) ABIH$\sb2$ was successfully obtained. Two novel cofacial binuclear complexes 1, with ML$\rm\sb{n}$ = $\eta\sp4$-1,5-cyclooctadiene)iridium and dicarbonylrhodium, have been synthesized. They are the first members of a new family of cofacial bimetallic complexes that may provide new models for redox-active enzymes, such as cytochrome oxidase.
