Popis:	Ru, Rh, and Ir complexes of ..pi..-bound thiophene (T) and benzo(b)thiophenes (BTs), (eta-C/sub 5/H/sub 5/)Ru(BT)/sup +/, (eta-C/sub 5/Me/sub 5/)M(BT)/sup 2 +/, and (eta-C/sub 5/Me/sub 2/)M(T)/sup 2 +/ (M = Rh, Ir), which serve as models for the adsorption of thiophenes on hydrodesulfurization (HDS) catalysts, have been synthesized. The Rh and IR compounds are the first dicationic transition metal complexes of either T or BTs. The BT ligands are bound to the transition metal centers via the benzene ring. The first X-ray structural characterization of a BT complex, ((eta-C/sub 5/H/sub 5/)Ru(eta/sup 6/-BT))BF/sub 4/ (1), is reported.
