1:1 Complexes of octafluoronaphthalene with trans-stilbene and trans-azobenzene

Co-crystallisation of octafluoronaphthalene (OFN) with trans-stilbene or trans-azobenzene from solutions yielded 1:1 molecular complexes, shown by single-crystal X-ray diffraction to contain infinite stacks of near-parallel and planar, alternating OFN and trans-stilbene or trans-azobenzene molecules.
