Triclinic polymorph of dibenzotetra-thia-fulvalene

Acta Crystallogr Sect E Struct Rep Online. 2009 Aug 8;65(Pt 9):o2083. doi: 10.1107/S1600536809030013.

Abstract

Crystals of the title compound (DBTTF), C(14)H(8)S(4), feature a triclinic polymorph different from two known monoclinic polymorphs. In this form, there are two independent centrosymmetric half-mol-ecules in the asymmetric unit. Although the mol-ecular orientations are relatively similar to one of monoclinic polymorphs, the packing motif is different.
