Heterobimetallic complexes supported by a multidentate tripodal ligand Benedict Thompson, Till Neumann, Rebecca A. Musgrave King's College London, UK Cooperative effects between two or more metal centres are of particular interest within the context of multiple electron transfer in small-molecule activation and catalysis. 1,2 The synthesis of bimetallic complexes pairing a first row transition metal ion (M 1 ) and a lanthanide metal ion (M 2 ) within a tripodal Schiff base ligand framework will be described (Figure 1). The structural characteristics of these complexes have been determined by single crystal X-ray diffraction and 1 H NMR spectroscopy. The optical and electrochemical properties have been probed by UV- Vis and IR spectroscopies and cyclic voltammetry respectively (with support from DFT calculations) with a view to determining the degree of interaction between (1) the two metal centres and (2) the metal centres and the ligand.
