摘要

We present a comprehensive single crystal packing study of the D-3h-symmetric anthracene-based hydrocarbon cyclophane "anthraphane". It was crystallized from 30 different solvents, yielding a total of 31 co-crystals (including polymorphs), which were analyzed by SC-XRD. The obtained layered crystal, structures were classified in seven afferent packing motifs according-to, the type of interactions that the anthracene units of anthraphane are engaged with, namely, CH center dot center dot center dot pi edge-to-face (etf) or pi center dot center dot center dot pi face-to-face (etf) interactions. Among the Seven packing motifs, three were found to be potentially photoreactive in terms of topochemical anthracene dimerization. To the best of our knowledge, this library of crystal structures is the most comprehensive crystal packing study ever performed on a single molecule and could be therefore used to validate the current methods of computational structure prediction, in particular, regarding the influence of the solvent in crystal packings.
