Crystal structure and Hirshfeld surface analysis and energy frameworks of 1-(2,4-dimethylphenyl)-4-(4-methoxyphenyl)naphthalene

Abstract

In the title compound, C25H22O, the two rings of the naphthalene system are inclined to each other by 3.06 (15)°. The mean plane of the naphthalene ring system makes a dihedral angle of 65.24 (12)° with the dimethylphenyl ring and 55.82 (12)° with the methoxyphenyl ring. The dimethylphenyl ring is inclined to the methoxyphenyl ring by 59.28 (14)°. In the crystal, adjacent molecules are linked via C—H...π interactions, forming chains along [100]. Using Hirshfeld surface and two-dimensional fingerprint plots, the presence of short intermolecular interactions in the crystal structure were analysed. The intermolecular interaction energies were also calculated and their distribution over the crystal structure was visualized graphically using energy frameworks.
