The structure of 4,5-diferrocenyl-1,2-dithiole-3-thione, [Fe2(C5H5)2(C13H8S3)] or C23H18Fe2S3, at 130 K has monoclinic (P21/c) symmetry. The molecule has two ferrocenyl units attached to a 1,2-dithiole-3-thione moiety. It is of interest with respect to the question if the introduction of ferrocenyl substituents into biologically active molecules offers the potential to obtain more efficacious therapeutic drugs. The crystal structure displays intermolecular contacts of the C—H...S and S—π(C—C) types.
