Crystal structure and Hirshfeld surface analysis of 4-(3-methoxyphenyl)-2,6-diphenylpyridine

Abstract

The title compound, C24H19NO, was obtained via the reaction of (1E,2E)-3-(3-methoxyphenyl)-1-phenylprop-2-en-1-one with ethyl 2-oxopropanoate, using NH4I as a catalyst. The compound crystallizes in the monoclinic space group I2/a. In the molecule, the four rings are not in the same plane, the pyridine ring being inclined to the benzene rings by 17.26 (6), 56.16 (3) and 24.50 (6)°. In the crystal, molecules are linked by C—H...π interactions into a three-dimensional network. To further analyse the intermolecular interactions, a Hirshfeld surface analysis was performed. Hirshfeld surface analysis indicates that the most abundant contributions to the crystal packing are from H...H (50.4%), C...H/H...C (37.9%) and O...H/H...O (5.1%) interactions.
