ABSTRACT: In the title compound C(37)H(32)Cl(2)N(2)O(4), the unsubstituted pyrrolidine ring shows a twist conformation whereas the substituted pyrrolidine ring shows an envelope conformation. The dimeth-oxy benzene ring is perpendicular to the tetra-lone ring, making a dihedral angle of 89.94?(5)°. Mol-ecules are linked into centrosymmetric dimers by N-H?O hydrogen bonds and the crystal structure is stabilized by C-H?? inter-actions and C-H?O hydrogen bonds. One meth-oxy group is disordered over two positions with the site occupancy factors of 0.84?(2) and 0.16?(2).

5,6-Dimeth-oxy-4',5'-diphenyl-indane-2-spiro-3'-pyrrolidine-2'-spiro-3''-indoline-1,2''-dione.

Project description:In the title compound, C(33)H(28)N(2)O(4), the central pyrrolidine ring adopts a half-chair conformation. Both the indolinone and indanone groups are twisted, with their five-membered rings adopting a half-chair and an envelope conformation, respectively. The two benzene rings and the mean plane of the indolinone and indanone groups make dihedral angles of 71.98?(10), 84.32?(10), 86.26?(9) and 78.50?(9)°, respectively, with the central pyrrolidine ring. Intra-molecular C-H?O hydrogen bonds stabilize the mol-ecular conformation. In the crystal, pairs of inter-molecular N-H?O hydrogen bonds link the mol-ecules into centrosymmetric dimers. The dimers are inter-connected into ribbons propagating along [110] via weak inter-molecular C-H?O hydrogen bonds. Weak inter-molecular C-H?? and ?-? [centroid-centroid distance = 3.6509?(11)?Å] inter-actions are also observed.

Project description:The title compounds, C20H16N2O3S, (I), and C21H18N2O3S, (II), differ by the presence of a methyl group in position 5 on the 1H-indole-2-one ring of compound (II). The two compounds have a structural overlap r.m.s. deviation of 0.48?Å. There is a significant difference in the conformation of the thia-zolidine ring: it has a twisted conformation on the fused N-C bond in (I), but an envelope conformation in compound (II) with the S atom as the flap. The planar pyrrolidine ring of the indole ring system is normal to the mean plane of the five-membered pyrrolidine ring of the pyrrolo-thia-zole unit in both compounds, with dihedral angles of 88.71?(9) and 84.59?(8)°. The pyran rings in both structures have envelope conformations with the methyl-ene C atom adjacent to the C=O group as the flap. In both compounds, there is a short intra-molecular C-H?O contact present. In the crystal of (I), mol-ecules are linked by C-H?O hydrogen bonds forming chains propagating along the b-axis direction. The chains are linked by N-H?? inter-actions, forming layers parallel to (10). In the crystal of (II), mol-ecules are linked by pairs of N-H?O hydrogen bonds, forming inversion dimers which are linked by C-H?O hydrogen bonds to form a three-dimensional structure.

1,1'-(Ethane-1,2-di-yl)bis-(indoline-2,3-dione).

Project description:The mol-ecule of the title compound, C(18)H(12)N(2)O(4), is situated on a crystallographic centre of symmetry. The mol-ecule has a zigzag structure, with two parallel symmetry-related indoline-2,3-dione fragments linked by an ethyl-ene group at each N atom. In the crystal, the mol-ecules stack in columns along the b axis. There are two such columns in the structure. The mol-ecules within each column are parallel; however, the mol-ecules in the two columns differ in the respective orientation of the indoline-2,3-dione fragments. In one column, they are approximately parallel to (112), while in the other they are approximately parallel to (12). The inter-planar angle between the indoline-2,3-dione fragments in the two columns is 80.83?(3)°. The mol-ecules within each column are related by mutual displacement of their centres of symmetry, that is (0, ±1/2, ±1/2). The packing between the mol-ecules is provided by weak inter-actions only, viz. C-H?O hydrogen bonds and ?-? [centroid-centroid distance = 3.8745?(8)?Å] and C=O?? inter-actions.

Project description:The asymmetric unit of the title compound, C(34)H(31)N(3)O(2), consists of two independent mol-ecules which differ slightly in the orientations of the phenyl rings with respect to the pyrrolidine ring.
