One approach to the removal of sulfur-containing compounds from transportation fuels involves the coordination of such compounds to transition metal complexes. We report the design and synthesis of a complex (eta(5)-C5H4CH2Ph)Ru(CO)(2)(eta(1)(S)-DBT)(+) that tests the concept that DBT binding through the sulfur can be augmented by pi-pi stacking interactions between a pendant phenyl group on the cyclopentadienyl ring and the DBT ligand. The crystal structure and kinetic binding studies of (eta(5)-C5H4CH2Ph)Ru(CO)(2)(DBT)(+) are reported and discussed.
