3-Carboxymethyl-1H-indole-4-carboxylic acid
In the title compound, C(11)H(9)NO(4), the carboxyl group bonded to the six-membered ring lies close to the plane of the 1H-indole ring system [dihedral angle = 13.13 (9)°], whereas the carb-oxy-lic acid group linked to the five-membered ring by a methyl-ene bridge is close to perpendicular [78.85 (9)°]. In the crystal, O-H⋯O and N-H⋯O hydrogen bonds link the mol-ecules, generating (110) sheets.

The title compound, C(7)H(9)N(3)O(2), was prepared by alkaline hydrolysis of ethyl 1-allyl-3-amino-1H-pyrazole-4-carboxyl-ate. The crystal structure is stabilized by three types of inter-molecular hydrogen bond (N-H⋯O, N-H⋯N and O-H⋯N).

The asymmetric unit of the title compound, C(9)H(8)N(2)O(2), contains two mol-ecules. In the crystal structure, both mol-ecules form inversion dimers via pairs of O-H⋯O hydrogen bonds, and a C-H⋯O inter-ation is also seen.

Two independent but very similar mol-ecules comprise the asymmetric unit of the title compound, C(17)H(15)NO(2)S. The mol-ecules have L-shapes with the dihedral angles between the fused-ring system (r.m.s. deviations = 0.036 and 0.019 Å, respectively) and the benzene ring being almost the same, i.e. 82.98 (12) and 84.46 (13)°, respectively. The terminal ethenyl group is almost coplanar with the...
متن کامل2-(4-Fluorophenyl)-3-methyl-1H-indole
The indole N-H hydrogen in the title compound, C(15)H(12)FN, does not display classical hydrogen bonding. Rather it forms an interaction with the π system of an adjacent indole, resulting in weakly inter-acting chains along the [001] direction.
