ABSTRACT: In the title compound, C31H22N4O4, the pyrrolidine ring adopts a twist conformation on the N-CH2 bond. The indolin-2-one and the 1H-indole rings are nearly planar (r.m.s. deviations = 0.06 and 0.011?Å, respectively) and are inclined to one another by 34.19?(9)°. The chromene ring system is also nearly planar (r.m.s. deviation = 0.029?Å). It is almost normal to the 1H-indole ring system, with a dihedral angle of 88.71?(8)°, and is inclined to the indolin-2-one ring system by 72.76?(8)°. In the crystal, mol-ecules are linked via N-H?O hydrogen bonds, forming slabs parallel to (10-1). The slabs are linked by C-H?O hydrogen bonds, forming a three-dimensional structure.

Project description:In the title compound, C26H20N4O2S, the central pyrrolidine ring adopts a twist conformation on the C-C bond involving the spiro C atom. Its mean plane makes dihedral angles of 78.83?(14), 65.91?(15) and 44.49?(18)° with the mean planes of the adjacent oxindole ring system, the indole system and the thio-phene ring, respectively.

In the oxindole fused-ring system, the pyrrole ring adopts an envelope conformation with the spiro C atom as the flap. In the crystal, pairs of N-H?O hydrogen bonds link the mol-ecules, forming inversion dimers with an R (2) 2(8) ring motif. The dimers are linked by further N-H?O hydrogen bonds, forming a two-dimensional network lying parallel to (100).

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.

Project description: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.

Project description:In the title compound, C(23)H(19)N(3)O(4), the pyran ring adopts a half-chair conformation, while the pyrrolidine (with a C atom as the flap atom) and the five-membered ring in the indoline (with a C atom as the flap atom) ring system adopt slight envelope conformations. The pyrrolidine ring makes dihedral angles of 83.3?(1) and 60.4?(1)° with the mean plane through all non-H atoms of the indoline and chromene ring systems, respectively. In the crystal, mol-ecules are connected by two unique N-H?O and O-H?O hydrogen-bonding inter-actions, which form centrosymmetric patterns described by graph-set motifs R(2) (2)(18) and R(2) (2)(14). These two motifs combine to form a hydrogen-bonded chain which propagates in the a-axis direction. The crystal structure is also stablized by C-H?O inter-actions and by aromatic ?-? stacking inter-actions between the pyran and benzene rings of neighbouring mol-ecules [centroid-centroid distance = 3.755?(1)?Å and slippage = 1.371?(2)?Å].
