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

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.
