Methyl 5-bromo-2-hydroxybenzoate
The title compound, C(8)H(7)BrO(3), is almost planar (r.m.s. deviation for the non-H atoms = 0.055 Å). In the crystal, O-H⋯O hydrogen bonds link the mol-ecules into C(6) chains propagating in [010]. Very weak aromatic π-π inter-actions [centroid-centroid distances = 3.984 (5) and 3.982 (5) Å] also occur.
متن کاملMethyl 5-chloro-2-nitrobenzoate
In the title compound, C(8)H(6)ClNO(4), the nitro and acet-oxy groups attached to the benzene ring at neighbouring positions are twisted from its plane by 29.4 (1) and 49.7 (1)°, respectively. In the crystal, weak C-H⋯O hydrogen bonds link mol-ecules into layers parallel to (101). The crystal packing exhibits short inter-molecular C⋯O distances of 2.925 (3) Å.

The title compound, C(7)H(5)BrClNO(2), crystallizes with two independent molecules in the asymmetric unit. In the absence of classical inter-molecular inter-actions, the crystal structure exhibits relatively short inter-molecular Br⋯O distances [3.143 (9) and 3.162 (9)Å].
متن کاملMethyl 5-chloro-2-(4-methylbenzenesulfonamido)benzoate
In the title compound, C(15)H(14)ClNO(4)S, the benzene rings are oriented at a dihedral angle of 85.42 (1)°. An intra-molecular N-H⋯O hydrogen bond results in the formation of a five-membered ring and an intramolecular C-H⋯O inter-action also occurs.
متن کامل2-Chloro-5-methyl-3-nitropyridine
The title compound, C(6)H(5)ClN(2)O(2), crystallizes with two independent mol-ecules in the asymmetric unit. Inter-molecular C-H⋯O hydrogen bonds stabilize the crystal structure.
