Abstract :
In this paper, we describe the synthesis of a new dihydro-2H-pyridazin-3-one derivative. The molecule, C18H16N2O, is not planar; the benzene and pyridazine rings are twisted with respect to each other, making a dihedral angle of 11.47 (2)°, and the toluene ring is nearly perpendicular to the pyridazine ring, with a dihedral angle of 89.624 (1)°. The molecular conformation is stabilized by weak intramolecular C—H⋯N contacts. In the crystal, pairs of N—H⋯O hydrogen bonds link the molecules into inversion dimers with an R22(8) ring motif. The intermolecular interactions were investigated using Hirshfeld surface analysis and two-dimensional (2D) fingerprint plots, revealing that the most important contributions for the crystal packing are from H⋯H (56.6%), H⋯C/C⋯H (22.6%), O⋯H/H⋯O (10.0%) and N⋯C/C⋯N (3.5%) interactions.
