Nature is the most successful chemist for activating and interconverting small molecules and a key feature of many enzymes that carry out these transformations is their asymmetric, bimetallic active sites, that is, two metal ions are present, each in a unique coordination environment. This presentation will describe our work to apply these lessons by developing a ligand that can hold two dissimilar metal ions in unique coordination environments. In particular, we will describe the synthesis of a ferrocene derivative wherein one cyclopentadienyl ring supports a dipicolylamine ligand and the other cyclopentadienyl ring supports a PNP ligand. We will also describe the coordination chemistry of our ligand with various transition metal ions, as well as computational results on the conformational flexibility of the system.
