Synthesis, non-spherical structure refinement and Hirshfeld surface analysis of racemic 2,2′-diisobutoxy-1,1′-binaphthalene

Abstract

In the racemic title compound, C28H30O2, the naphthyl ring systems subtend a dihedral angle of 68.59 (1)° and the molecular conformation is consolidated by a pair of intramolecular C—H...π contacts. The crystal packing features a weak C—H...π contact and van der Waals forces. A Hirshfeld surface analysis of the crystal structure reveals that the most significant contributions are from H...H (73.2%) and C...H/H...C (21.2%) contacts.
