1,2-Bis{4-[1-(anthracen-9-ylmethyl)-1H-1,2,3-triazol-4-yl]phenyl}-1,2-bis[4,5-bis(methylsulfanyl)-1,3-dithiol-2-ylidene]ethane

Abstract: The title molecule, C₅₈H₄₄N₆S₈, has point symmetry 2 (in the Schönfliess notation C₂). The related crystallographic twofold axis bisects the central ethane bond while it is parallel to the monoclinic unique axis of the unit cell. The dithiole=C-C=dithiole torsion angle is 103.7 (4)° and the triazole-anthracene moieties adopt a pincer-like conformation. The crystal structure features C-HS and C-HN contacts. The distance between the stacked anthracene fragments [centroid-centroid separations of 3.6871 (19) Å, off-set by 1.516 (3) Å and mean anthracene plane-plane separations of 3.361 (2) Å], which are parallel to (101) and (-101), indicates intermolecular anthracene-anthracene [pi] - [pi] contacts. One of the terminal methylsulfanyl groups was modelled as being disordered with two refined orientations that converged to occupancies of 0.809 (5) and 0.191 (5).
