چکیده
The title compound, C(10)H(11)ClN(2)O(2), features an almost planar C(ar)-N(H)-N=C(Cl) unit [torsion angle = 0.8 (1)° whose phenyl substituent is almost coplanar with it [dihedral angle = 2.8 (2)°]; this unit is slightly twisted with respect to the carboxyl -CO(2) fragment [dihedral angle = 10.3 (2)°]. In the crystal, the amino group acts as a hydrogen-bond donor to the carbonyl O atom of an adjacent mol-ecule; the hydrogen bond generates a helical chain that runs along the b axis of the monoclinic unit cell.

The mol-ecule of the title compound, C11H13ClN2O3, is planar (r.m.s. deviation = 0.0587 Å for non-H atoms) and adopts a Z conformation about the C=N double bond. In the crystal, mol-ecules are linked via an N-H⋯O hydrogen bond, forming zigzag chains propagating along [010]. These chains are consolidated by C-H⋯O hydrogen bonds.

The title compound, C(9)H(9)ClN(2)O, is close to planar (r.m.s. deviation for the non-H atoms = 0.0446 Å); it exists in a cis conformation with respect to the C=N double bond. In the crystal, the ketone O atom accepts both N-H⋯O and C-H⋯O hydrogen bonds, which leads to [010] infinite chains incorporating R(2) (1)(6) loops. The crystal structure also features a C-H⋯π inter-action.

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.
