Abstract
AbstractFive peri‐substituted naphthalene and acenaphthalene complexes (Ph2Pn)2Naph (E=Sb 1, Bi 3), (Ph2Sb)2Acenaph (2), (Ph2Bi)(Me3Sn)Naph (4) and (PhBiNaph)2 (5) were synthesized and characterized in solution (1H, 13C NMR, IR) and in the solid‐state (sc‐XRD). 1–5 show different types of noncovalent intermolecular interactions in the solid‐state including Naph−H⋅⋅⋅π, π⋅⋅⋅π and Bi⋅⋅⋅π (5) contacts, which were exemplarily (5) quantified by use of density functional theory and local coupled cluster electronic structure theory calculations, demonstrating that the Bi⋅⋅⋅π contact provides the main stabilizing contribution. Symmetry‐adapted intermolecular perturbation theory calculations showed that this and other contacts are dominated by London dispersion interactions.
