4'-(1H-Imidazol-2-yl)-3'-[(1H-indol-3-yl)carbon-yl]-1'-methyl-2-oxo-spiro-[indoline-3,2'-pyrrolidine]-3'-carbo-nitrile 0.15-hydrate.

ABSTRACT: In the title compound, C25H20N6O2·0.15H2O, the dihedral angles between the least-squares planes of the indole and pyrrolidine rings and between the oxindole and imidazole rings are 77.66?(7) and 45.31?(7)°, respectively. The pyrrolidine ring and the fused five-membered pyrrolidine ring of the oxindole moiety exhibit twisted conformations. The amide N atom is involved in both intra- and inter-molecular hydrogen bonding, having a bifurcated character. The mol-ecular structure is characterized by an intra-molecular N-H?O hydrogen bond, which generates an S(7) ring motif while an inter-molecular N-H?O hydrogen bond links the organic and solvent water mol-ecules. In the crystal, N-H?N hydrogen bonds generate a zigzag chain running parallel to c-axis direction. The H atoms of the solvent water mol-ecule were not located.
