Crystal structure and Hirshfeld surface analysis and energy frameworks of 1-(2,4-di-methyl-phen-yl)-4-(4-meth-oxy-phen-yl)naphthalene.

In the title compound, CHO, 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 di-methyl-phenyl ring and 55.82 (12)° with the meth-oxy-phenyl ring. The di-methyl-phenyl ring is inclined to the meth-oxy-phenyl ring by 59.28 (14)°. In the crystal, adjacent mol-ecules are linked C-H⋯π inter-actions, forming chains along [100]. Using Hirshfeld surface and two-dimensional fingerprint plots, the presence of short inter-molecular inter-actions in the crystal structure were analysed. The inter-molecular inter-action energies were also calculated and their distribution over the crystal structure was visualized graphically using energy frameworks.
