Popis: | In the crystal structure, C—HMthphn⋯OMthphn (Mthphn = methoxyphenyl) hydrogen bonds form corrugated layers parallel to (100) that are connected along the a axis by C—H⋯π(ring) and π–π stacking interactions. In the title molecule, C20H21N3O3, the allyl substituent is rotated out of the plane of its attached phenyl ring [torsion angle 100.66 (15)°]. In the crystal, C—HMthphn⋯OMthphn (Mthphn = methoxyphenyl) hydrogen bonds lead to the formation of (100) layers that are connected into a three-dimensional network by C—H⋯π(ring) interactions, together with π–π stacking interactions [centroid-to-centroid distance = 3.7318 (10) Å] between parallel phenyl rings. Hirshfeld surface analysis indicates that the most important contributions to the crystal packing are from H⋯H (48.7%) and H⋯C/C⋯H (23.3%) interactions. Computational chemistry reveals that the C—HMthphn⋯OMthphn hydrogen bond energy is 47.1 kJ mol−1. The theoretical structure, optimized by density functional theory (DFT) at the B3LYP/ 6–311 G(d,p) level, is compared with the experimentally determined molecular structure. The HOMO–LUMO behaviour was elucidated to determine the energy gap. |
