Crystal structure of a new polymorph of di(thio-phen-3-yl) ketone.


ABSTRACT: The crystal structure of the title compound, C9H6OS2, represents a new polymorph. The crystal structure was solved in the ortho-rhom-bic space group Pbcn with one half of the mol-ecule in the asymmetric unit. The thio-phene rings are perfectly planar and twisted with respect to each other, showing the mol-ecule to be in an S,O-trans/S,O-trans conformation. In the crystal, C-H?O hydrogen bonds connect the mol-ecules into layers extending parallel to the ab plane. The crystal structure also features ?-? inter-actions.
