Microwave Synthesis of Mixed Carboxylato Osmium-Containing Sawhorse Compounds
Abstract
Three new osmium-containing sawhorse complexes of the formula Os2(μ- O2CR1)(μ-O2CR2)(CO)4(L)2 were synthesized using microwave radiation. These complexes are the first examples of mixed-carboxylate ligand sawhorse complexes and offer a proof-of-concept to the idea of “cluster customization.” The structures of these compounds are analyzed for their properties including how they interact with solvent molecules and how different axial ligands affect the amount of disorder in their crystal structures. Several follow-up investigations, including experiments using dicarboxylate ligands and axially connected sawhorse complexes, are described.
