Arene-perfluoroarene interactions in crystal engineering. Part 3. Single-crystal structures of 1 : 1 complexes of octafluoronaphthalene with fused-ring polyaromatic hydrocarbonsFor part 1, see ref. 1. For part 2, see ref. 2. Presented at the 16th International Symposium on Fluorine Chemistry, University of Durham, UK, 16–21 July 2000, Abstract no. 308.Electronic supplementary information (ESI) available: experimental data for the re-determination of the crystal structure of triphenylene, tables of the average bond lengths in OFN and the polyaromatic molecules in both the complexes and pure compounds, and a table of distances and angles for intermolecular H···F contacts in the complexes which are below the sum of the van der Waals radii.
