with diiron nonacarbonyl to afford binuclear complexes resulting from coordination of the carbon—sulfur double bond to the two iron atoms and donation of two electrons from the S-alkyl group to one iron center. This novel mode of complexation creates a carbon—iron single bond and a chiral center at the carbon atom bonded to the metal, as shown by the spectroscopic studies and by an X-ray structure determination
