A Variable Bridging Ligand (VBL) strategy has been developed, for the purpose of preparing bimetallic and trimetallic complexes that would mimic the active site of various enzymes. The idea behind this synthetic method is to facilitate the access to biomimetic / bioinspired complexes. A cartoon representation of the VBL strategy is depicted on the top in the Figure below, while its experimental implementation is detailed at the bottom.

In a first step a pro-metalloligand is prepared from a primary metallic center and a main ligand. If this complex is coordinatively unsaturated, an additional, labile ligand (e.g., a coordinating solvent molecule) will be present to satisfy the coordination requirements of the metallic center. Then, this labile ligand can be easily replaced by a series of multitopic bridging ligands, thus generating a set of metalloligands that can be used to prepare the desired final complexes, by bringing into play other metallic centers, accompanied (or not) by additional ligands.

This presentation will describe our results in the preparation and characterization of several such complexes, synthesized using the above strategy, and highlight some of the challenges encountered so far in the preparation and characterization of the desired biomimetic / bioinspired complexes.
