Crystal structure and Hirshfeld surface analysis of 3-[2-(3,5-di-methyl-phen-yl)hydrazinyl-idene]benzo-furan-2(3H)-one.

In the title compound, C16H14N2O2, the 2,3-di-hydro-1-benzo-furan ring system is essentially planar and makes a dihedral angle of 3.69 (7)° with the di-methyl-phenyl ring. The mol-ecular conformation is stabilized by an intra-molecular N-H⋯O hydrogen bond with an S(6) ring motif. In the crystal, mol-ecules are connected by C-H⋯π and π-π stacking inter-actions, forming a layer lying parallel to the (11) plane. One methyl group is disordered over two orientations, with occupancies of 0.67 (4) and 0.33 (4). Hirshfeld surface analysis indicates that the most important contributions to the crystal packing are from H⋯H (51.2%), O⋯H/H⋯O (17.9%), C⋯H/H⋯C (15.2%) and C⋯C (8.1%) contacts. © Atioğlu et al. 2021.
