2-Amino-5-nitrobenzoic acid
In the title compound, C(7)H(6)N(2)O(4), an intra-molecular N-H⋯O hydrogen bond generates an S(6) ring. In the crystal, inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R(2) (2)(8) loops. Inter-molecular N-H⋯O and C-H⋯O hydrogen bonds then link the dimers, generating R(3) (3)(16)R(2) (1)(6) motifs. The whole mol-ecule is essentially planar, with the greatest deviation from the ...
متن کامل2-Amino-5-fluorobenzoic acid
In the title compound, C7H6FNO2, the mol-ecule is almost planar (r.m.s. deviation for the non-H atoms = 0.015 Å) and an intra-molecular N-H⋯O hydrogen bond closes an S(6) ring. In the crystal, inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R2(2)(8) loops. Weak N-H⋯F hydrogen bonds, short F⋯F contacts [2.763 (2) Å] and aromatic π-π stacking inter-actions [centroid-centroid sep...

In the title mol-ecule, C(3)H(5)N(5)O(2), the tetra-zole ring and carboxyl group form a dihedral angle of 82.25 (14)°. In the crystal, adjacent mol-ecules are linked through O-H⋯N, N-H⋯O and N-H⋯N hydrogen bonds into layers parallel to the bc plane.
متن کامل2-Amino-5-chloropyridine–fumaric acid (1/2)
The asymmetric unit of the title compound, C(5)H(5)ClN(2)·0.5C(4)H(4)O(4), comprises a neutral 2-amino-5-chloro-pyridine mol-ecule and one half of a fumaric acid mol-ecule which lies on an inversion center. The dihedral angle between the pyridine ring and the plane formed by the fumaric acid mol-ecule is 3.22 (8)°. The 2-amino-5-chloro-pyridine mol-ecule is planar, with a maximum deviation of 0...
متن کامل5-[(E)-(2-Fluorobenzylidene)amino]-2-hydroxybenzoic acid
In the title compound, C(14)H(10)FNO(3), the dihedral angle between the two benzene rings is 32.66 (14)°. An S(6) ring motif is formed due to an intra-molecular O-H⋯O hydrogen bond between the hy-droxy and carbonyl groups. In the crystal, mol-ecules are consolidated into dimers with R(2) (2)(8) ring motifs by pairs of O-H⋯O hydrogen bonds.
