Add to ORKGThe crystal and molecular structure of perylene has been refined from new three-dimensional data, confirming the gross features of the structure previously determined from two projections. The positional and thermal parameters of the carbon atoms have been refined by least-squares and differential syntheses and the hydrogen atoms have been approximately located. There are small but significant deviations from a completely planar arrangement; seemingly a result of slight intermolecular steric effects. A comparison of the measured bond lengths with those predicted by the valence-bond and molecular-orbital theory shows fairly close agreement with both sets of figures; the peri-bond lengths are 1.471-0.005 Å. In a similar vein the molecular st...
