crystallography and multinuclear NMR spectroscopy, IR spectroscopy and MS. X‐ray data for 1, 2, n O, n S, n Se (n=1–3) are compared. Eleven molecular structures have been analysed by naphthalene ring torsions, peri‐atom displacement, splay angle magnitude, X⋅⋅⋅E interactions, aromatic ring orientations and quasi‐linear arrangements. An increase in the congestion of the peri region following the introduction
