Özet
The central tetrahydropyridine ring of the title compound, C19H17N3O2, adopts a screw-boat conformation. In the crystal, strong C-H center dot center dot center dot O and N-H center dot center dot center dot N hydrogen bonds form dimers with R-2(2)(14) and R-2(2)(12) ring motifs, respectively, between consecutive molecules along the c-axis direction. Intermolecular N-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonds connect these dimers, forming a three-dimensional network. C-H center dot center dot center dot pi interactions and pi-pi stacking interactions contribute to the stabilization of the molecular packing. A Hirshfeld surface analysis indicates that the contributions from the most prevalent interactions are H center dot center dot center dot H (47.1%), C center dot center dot center dot H/H center dot center dot center dot C (20.9%), O center dot center dot center dot H/H center dot center dot center dot O (15.3%) and N center dot center dot center dot H/H center dot center dot center dot N (11.4%).
