Crystal structure and Hirshfeld surface analysis of 4-(3-meth-oxy-phen-yl)-2,6-di-phenyl-pyridine

The title compound, C₂₄H₁₉NO, was obtained via the reaction of (1E,2E)-3-(3-meth-oxy-phen-yl)-1-phenyl-prop-2-en-1-one with ethyl 2-oxo-propano-ate, using NH₄I as a catalyst. The compound crystallizes in the monoclinic space group I2/a. In the mol-ecule, 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, mol-ecules are linked by C-H⋯π inter-actions into a three-dimensional network. To further analyse the inter-molecular inter-actions, 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%) inter-actions.
