5-Chloro-2-nitrophenol
The asymmetric unit of the title compound, C(6)H(4)ClNO(3), contains two independent mol-ecules in which the dihedral angles between the benzene ring and the nitro groups are 2.5 (1) and 8.5 (1)°. Intra-molecular O-H⋯O hydrogen bonds involving the hy-droxy and nitro substituents result in the formation of S(6) six-membered rings. In the crystal, O-H⋯O, O-H⋯Cl and C-H⋯O hydrogen bonds together w...
متن کامل2-Chloro-5-nitropyridine
The non-H atoms of the title compound, C(5)H(3)ClN(2)O(2), almost lie in a common plane (r.m.s. deviation = 0.090 Å). In the crystal, adjacent mol-ecules feature a short Cl⋯O contact [3.068 (4) Å], forming a chain; these chains are consolidated into a layer structure by non-classical C-H⋯O inter-actions.

The mol-ecule of the title compound, C(6)H(5)ClN(2)O(2), is close to being planar (rms deviation = 0.032 Å for all non-H atoms), with a maximum deviation of -0.107 (3) Å for an O atom. In the crystal structure, inter-molecular N-H⋯O and N-H⋯N inter-actions link the mol-ecules into a three-dimensional network.

In the 5-chloro-salicylate anion of the title salt, C5H6BrN2 (+)·C7H4ClO3 (-), an intra-molecular O-H⋯O hydrogen bond with an S(6) graph-set motif is formed, so that the anion is essentially planar with a dihedral angle of 1.3 (5)° between the benzene ring and the carboxyl-ate group. In the crystal, the protonated N atom and the 2-amino group of the cation are hydrogen bonded to the carboxyl-at...

In the mol-ecule of the title compound, C(13)H(9)ClINO(4)S, the coordination around the S atom is distorted tetra-hedral. The aromatic rings are oriented at a dihedral angle of 74.46 (9)°. Intra-molecular C-H⋯O hydrogen bonds result in the formation of two five- and one six-membered rings, which adopt planar, envelope and twisted conformations, respectively. In the crystal structure, inter-mole...
