3-[3-(3-Fluorophenyl)-1,2,4-oxadiazol-5-yl]propionic acid
In the title compound, C(11)H(9)FN(2)O(3), the benzene ring is almost coplanar with the heterocyclic ring, making a dihedral angle of 14.0 (1)°. The plane of the carboxyl group is rotated by 14.7 (3)° with respect to the 1,2,4-oxadiazole ring plane. The aliphatic chain exhibits a standard zigzag arrangement. Two inter-molecular O-H⋯O hydrogen bonds between the carboxyl groups related by an inve...

The title compound, C(8)H(6)N(4)O(2), is a difunctional compound with a carboxyl-ate and a tetra-zole residue. In the crystal structure, mol-ecules are linked into two-dimensional sheets by inter-molecular N-H⋯O and O-H⋯N hydrogen bonds.
متن کامل5-Methyl-3-phenylisoxazole-4-carboxylic acid
In the title compound, C11H9NO3, the phenyl and isoxazole rings form a dihedral angle of 56.64 (8)°. The carb-oxy group is almost in the same plane as the isoxazole ring with a C-C-C-O torsion angle of -3.3 (2)°. In the crystal, pairs of O-H⋯O hydrogen bonds link the mol-ecules into head-to-head dimers. C-H⋯N hydrogen bonds and π-π stacking inter-actions between phenyl rings [centroid-centroid ...
متن کامل5-Chloro-1H-indole-3-carboxylic acid
In the title compound, C(9)H(6)ClNO(2), the carboxyl group is twisted from the indole ring system by 9.00 (8)°. In the crystal, inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R(2) (2)(8) loops and N-H⋯O hydrogen bonds link the dimers into (001) sheets. Aromatic π-π stacking inter-actions [centroid-centroid distance = 3.7185 (12) A °] are also observed.
متن کامل5-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.
