Crystal structure of dibenzo[c,e]thiepine-5(7H)-thione

Abstract

The title compound, C14H10S2, was prepared from dibenzo[c,e]oxepine-5(7H)-one and Lawesson's reagent in refluxing toluene. Pink blocks were grown by slow evaporation from petroleum ether. The resulting crystal structure resides in the orthorhombic space group Pbca with Z = 8 and Z′ = 1. The structure is comprised of a network of C—H...S and C—H...π interactions. No π–π interactions between ring moieties were observed, most likely due to the lack of molecular planarity.
