5-Fluoro-1H-indole-3-carboxylic acid
In the title compound, C(9)H(6)FNO(2), the carboxyl group is twisted slightly away from the indole-ring plane [dihedral angle = 7.39 (10)°]. In the crystal, carboxyl inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R(2) (2)(8) loops and N-H⋯O hydrogen bonds connect the dimers into (10[Formula: see text]) sheets.

The 3-methyl-butanoyl group and the 5-fluoro-uracil unit of the title compound, C(9)H(11)FN(2)O(3), are essentially coplanar, with the carbonyl group oriented towards the ring CH group and away from the nearer ring carbonyl group. The 3-methyl-butanoyl (C=)C-N-C=O torsion angle of 9.6 (2)° is comparable to that in structurally related compounds. In the solid state, two inversion-related mol-ecu...
متن کامل6-Fluoro-1H-indole-3-carboxylic acid
In the title compound, C(9)H(6)FNO(2), all the non-H atoms are approximately coplanar, the carb-oxy O atoms deviating by 0.0809 and -0.1279 Å from the indole plane. In the crystal, O-H⋯O hydrogen bonds link the mol-ecules into dimers which are linked via N-H⋯O hydrogen bonds and π-π inter-actions [centroid-centroid distance = 3.680 (2) Å].

The penta-noyl group and the 5-fluoro-uracil moiety of the title compound, C(9)H(11)FN(2)O(3), are essentially coplanar, with the penta-noyl carbonyl group oriented towards the ring CH group and away from the nearer ring carbonyl group. In the crystal structure, two inversion-related mol-ecules form a dimer structure, in which two N-H⋯O hydrogen bonds generate an inter-molecular R(2) (2)(8) rin...
متن کامل5-Bromo-1H-indole-3-carbaldehyde thiosemicarbazone
In the essentially planar title mol-ecule, C(10)H(9)BrN(4)S, the C=N double bond is in a trans configuration. In the crystal structure, the S atom acts as a hydrogen-bond acceptor for the aromatic NH, aliphatic NH and terminal NH(2) groups of three symmetry-related mol-ecules, forming a weak hydrogen-bonded layer structure.
