Abstract: The title compound, C26H29N3O2, crystallizes with two molecules in the asymmetric unit, having C-HO interactions between them and resulting in a dimer characterized by an R22(11) motif. These dimers are linked into an ABABAB chain via N-HO, N-HN and C-HO built edge-fused R12(5) and R22(7) motifs. This chain is linked to its inversion-related partner via N-HO bonds with an R22(8) motif and leads to a double chain extending along the b axis characterized by an R66(36) motif across the inversion centres. The methyl group of the phenyl ring and the oxindole of molecule A and B are involved in C-H interactions. One C atom of the pyrrolizine ring of molecule A and its attached H atoms show positional disorder, the major and minor components being in the ratio 0.706 (7):0.294 (7).
