2-(2-Chlorophenyl)-5-methyl-1,3-dioxane-5-carboxylic acid
In the title compound, C(12)H(13)ClO(4), the 1,3-dioxane ring adopts a chair conformation and the 2-chloro-benzene and methyl substituents occupy equatorial sites. The carboxyl group is in an axial inclination. In the crystal, carb-oxy-lic acid inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R(2) (2)(8) loops.

The title compound, C(8)H(8)N(2)O(4), is almost planar (r.m.s. deviation = 0.037 Å) and 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 hydrogen bonds (involving the same H atom that forms the intra-molecular hydrogen bond) link the dimers into infinite sheet...
متن کامل5-Chloro-2-hydroxybenzoic acid
The asymmetric unit of the title compound, C(7)H(5)ClO(3), contains two mol-ecules; both feature an intra-molecular O-H⋯O hydrogen bond, which generates an S(6) ring. In the crystal, both mol-ecules form inversion dimers linked by pairs of O-H⋯O hydrogen bonds with R(2) (2)(8) ring motifs. The dimers are inter-linked by C-H⋯O inter-actions.
متن کامل2-Allyloxy-5-nitrobenzoic acid
The mol-ecule of the title compound, C(10)H(9)NO(5), is approximately planar, with the mean planes of the nitro, carboxyl and all-yloxy groups rotated by 8.1 (3), 7.9 (3) and 4.52 (18)°, respectively, from the plane of the benzene ring. Bond lengths in the aromatic ring are influenced by both electronic effects and strain induced by ortho-substitution. In the crystal structure, centrosymmetrica...
متن کامل2-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 ...
