ABSTRACT: In the title compound C38H32N4O3, one pyrrolidine ring adopts an envelope conformation with the N atom as the flap while other pyrrolidine ring adopts an twisted conformation. The pyrrolizine ring forms dihedral angles of 79.24?(5) and 77.57?(5)° with the chromene and indole rings, respectively. The carbonyl O atoms deviate from the least-square planes through the chromene and indole rings by 0.0113?(12) and 0.0247?(12)?Å, respectively. In the crystal, non-classical C-H?O inter-actions link the mol-ecules, generating an C(9) chain along the b-axis direction.

Project description:The title compound, C(26)H(29)N(3)O(2), crystallizes with two mol-ecules in the asymmetric unit, having C-H⋯O inter-actions between them and resulting in a dimer characterized by an R(2) (2)(11) motif. These dimers are linked into an ABABAB chain via N-H⋯O, N-H⋯N and C-H⋯O built edge-fused R(1) (2)(5) and R(2) (2)(7) motifs. This chain is linked to its inversion-related partner via N-H⋯O bonds with an R(2) (2)(8) motif and leads to a double chain extending along the b axis characterized by an R(6) (6)(36) motif across the inversion centres. The methyl group of the phenyl ring and the oxindole of mol-ecule A and B are involved in C-H⋯π inter-actions. One C atom of the pyrrolizine ring of mol-ecule A and its attached H atoms show positional disorder, the major and minor components being in the ratio 0.706 (7):0.294 (7).

The pyrazole ring forms dihedral angles of 42.36?(7) and 24.07?(8)° with its C- and N-attached phenyl groups, respectively. The solvent water mol-ecule has a partial occupancy of 0.75. In the crystal, the water mol-ecules link the fused-ring mol-ecules into chains along the b axis via O-H?N and O-H?O hydrogen bonds. The crystal packing is further stabilized by C-H?? inter-actions involving a methyl-ene group of the pyran ring and the C-attached benzene ring on the pyrazole ring.

The acenapthylene ring system is approximately planar [maximum deviation = 0.058?(2)?Å] and forms dihedral angles of 85.9?(1) and 48.5?(1)°, respectively, with the pyrollothia-zole and chromene ring systems. The mol-ecular conformation is stabilized by three weak intra-molecular C-H?O hydrogen bonds, which generate one S(8) and two S(6) ring motifs.

The crystal packing also features pairs of C-H?? inter-actions, which link the dimers into a supra-molecular chain along the b axis.
