Crystal structure and Hirshfeld surface analysis of ethyl 6′-amino-2′-(chloromethyl)-5′-cyano-2-oxo-1,2-dihydrospiro[indoline-3,4′-pyran]-3′-carboxylate

ABSTRACT: The molecules are connected in the crystal by N—H⋯O hydrogen-bond pairs along the b-axis direction as dimers with The molecular conformation of the title compound, C17H14ClN3O4, is stabilized by an intramolecular C—H⋯O contact, forming an S(6) ring motif. In the crystal, the molecules are connected by N—H⋯O hydrogen-bond pairs along the b-axis direction as dimers with R22(8) and R22(14) ring motifs and as ribbons formed by intermolecular C—H⋯N hydrogen bonds. There are weak van der Waals interactions between the ribbons. The most important contributions to the surface contacts are from H⋯H (34.9%), O⋯H/H⋯O (19.2%), C⋯H/H⋯C (11.9%), Cl⋯H/H⋯Cl (10.7%) and N⋯H/H⋯N (10.4%) interactions, as concluded from a Hirshfeld surface analysis.
