1-Ethyl-4'-(1H-indol-3-ylcarbon­yl)-1'-methyl-2,2''-dioxodi­spiro­[indoline-3,2'-pyrrolidine-3',3''-indoline]-4'-carbo­nitrile dimethyl sulfoxide monosolvate

Abstract: In the title compound, C31H25N5O3·C2H6OS, the three indole/indoline units are all essentially planar with maximum deviations of 0.0172 (3), 0.053 (2) and 0.07 (2) Å. The pyrrolidine ring adopts an envelope conformation with the C atoms bearing the 1-ethyl-2-oxo­indole substituent (in which the five-membered ring adopts a twisted conformation) as the flap. The dimethyl sulfoxide solvent mol­ecule is disordered over two positions, with an occupancy factor ratio of 0.871 (4):0.129 (4). The solvent components are linked to the heterocyclic mol­ecule via C-H...O and C-H...S hydrogen bonds. In the crystal, the solvent components are linked to the heterocyclic molecule via C-H...O and C-H...S inter­actions, forming R22(10) ring motifs. The mol­ecules are further connected into a chain along the a-axis direction via N-H...O hydrogen bonds.
