1′-Acetyl-3-phenyl-6-oxa-4-thia-2-azaspiro[bicyclo[3.2.0]hept-2-ene-7,3′-indolin]-2′-one
In the title indoline compound, C(19)H(14)N(2)O(3)S, the pyrrolidine ring adopts an envelope conformation with the four-connected (spiro) C atom as the flap [displacement = 0.148 (3) Å]. The mean plane formed through the indoline unit is inclined at dihedral angles of 89.92 (16) and 59.54 (12)° with the thia-zole and phenyl rings, respectively; the dihedral angle between the latter rings is 9.5...
متن کامل2-Benzyl-6-benzyloxypyridazin-3(2H)-one
In the title compound, C(18)H(16)N(2)O(2), the central pyridazine ring forms dihedral angles of 77.08 (5)° and 84.62 (5)° with the two benzene rings. The dihedral angle between the two benzene rings is 68.18 (4)°. A very weak intra-molecular C-H⋯N hydrogen bond and an intra-molecular C-H⋯π inter-action occur. The crystal structure is stabilized by weak inter-molecular C-H⋯O hydrogen bonds and w...
متن کامل6-Hydroxy-3-(hydroxyimino)indolin-2-one
In the title compound, C(8)H(6)N(2)O(3), the indol-2-one system is almost planar [maximum deviation = 0.010 (3) Å]. In the crystal structure, inter-molecular N-H⋯O, O-H⋯N and O-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network. π-π contacts between the indole ring systems [centroid-centroid distances = 3.494 (1), 3.731 (1) and 3.736 (1) Å] may further stabilize the structure.

In the title compound, C(17)H(14)N(2)O(2), the central pyridazine ring forms dihedral angles of 47.29 (5) and 88.54 (5)° with the benzene rings, while the dihedral angle between the benzene rings is 62.68 (6)°. In the crystal, molecules are linked by two weak C-H⋯O hydrogen bonds and three weak C-H⋯π inter-actions.
