A 2:1 cocrystal of 6,13-dihydropentacene and pentacene

Abstract

6,13-Di­hydro­pentacene and pentacene cocrystallize in a ratio of 2:1, i.e. C22H16·0.5C22H14, during vapour transport of commercial pentacene in a gas flow. The crystal structure is monoclinic, space group P21/n, and contains one di­hydro­pentacene mol­ecule and half a pentacene mol­ecule in the asymmetric unit.
