Triclinic polymorph of dibenzotetra-thia-fulvalene

Abstract

Crystals of the title compound (DBTTF), C14H8S 4, feature a triclinic polymorph different from two known monoclinic polymorphs. In this form, there are two independent centrosymmetric half-molecules in the asymmetric unit. Although the mol-ecular orientations are relatively similar to one of monoclinic polymorphs, the packing motif is different. © Mamada and Yamashita 2009.
