3-(Phenylimino)indolin-2-one
The imino C=N double bond in the title compound, C(14)H(10)N(2)O, exists in an E conformation, with the phenyl ring being twisted by 80.7 (1)° in one independent mol-ecule and by 81.4 (1)° in the other with respect to the plane of the indoline fused-ring system. The two independent mol-ecules are linked by N-H⋯O hydrogen bonds, forming a zigzag chain running along the a axis.

The title mol-ecule, C(21)H(15)NO, has an indoline-2-one and two benzene substituent groups which are arranged in a propeller-like fashion around the central C atom. The dihedral angle between the two benzene rings is 73.32 (16)° and those between the benzene rings and the indoline-2-one group are 76.54 (14) and 67.69 (14)°. In the crystal, there is an inter-molecular N-H⋯O hydrogen-bonding int...
متن کامل3-Hydroxy-3-[(2-methylpropanoyl)methyl]indolin-2-one
The title compound, C(13)H(15)NO(3), was synthesized by the Aldol reaction of isatin and 3-methyl-butan-2-one refluxing in methanol catalyzed by dimethyl-amine. The packing of the mol-ecules in the crystal structure features inter-molecular N-H⋯O and O-H⋯O hydrogen bonds.

In the title compound, C16H15N3O, the dihedral angle between the indole ring system (r.m.s. deviation = 0.020 Å) and the phenyl ring is 14.49 (9)°. The mol-ecular conformation is supported by an intra-molecular C-H⋯O inter-action, which closes an S(7) ring. In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds generate R2(2)(8) loops.
متن کامل3-[(E)-Benzylidene]indolin-2-one
In the title indolin-2-one derivative, C(15)H(11)NO, the phenyl ring and the oxoindoline fused-ring system (r.m.s. deviation = 0.011 Å) are aligned at 48.52 (6)°. In the crystal, inversion-related mol-ecules form an N-H⋯O hydrogen-bonded dimer via an eight-membered {⋯HNCO}(2) synthon. The dimeric aggregates are linked into a three-dimensional architecture via C-H⋯O and π-π inter-actions between...
