4,5-Diferrocenyl-1,2-dithiole-3-thione

IUCrData, 2022
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

1-Methyl-3-phenylimidazolidine-2-thione [PDF]

Acta Crystallographica Section E Structure Reports Online, 2014
The asymmetric unit of the title cyclic thiourea derivative, C10H12N2S, comprises two molecules, each of which has a twist about the CH2—CH2bond within the five-membered ring. The major difference between the independent molecules is manifested in the relative orientations of the five- and six-membered rings [dihedral angles between the least-squares ...
