TL;DR: An X-ray crystallographic analysis of the title compound (1) shows that this fused-ring polycyclic molecule is greatly distorted from planarity as discussed by the authors, and the structure is centrosymmetric and the mean plane of the center ring is twisted by approximately 48° relative to the plane determined by the terminal atoms of the pentacene nucleus.
