Synthesis, crystal structure and crystal packing of diaza[5]helicenes / C. Bazzini, T. Caronna, F. Fontana, P. Macchi, A. Mele, I. Natali Sora, W. Panzeri, A. Sironi. - In: NEW JOURNAL OF CHEMISTRY. - ISSN 1144-0546. - 32:10(2008), pp. 1710-1717. [10.1039/b800050f]
Abstract:
Analysis of the crystalline packing of known aza[5]helicenes is presented together with some
newly synthesized diaza[5]helicenes species, characterized by NMR spectroscopy and X-ray
diffraction. The comparison with carbo[5]helicenes and monoaza[5]helicenes emphasizes the
importance of the ‘‘shape factor’’ (responsible of the isomorphism between some species in the
series) as well as the lack of a unique supramolecular effect organizing the molecules in the
crystals (responsible for the polymorphism observed for some compounds).
