2-Chloro-5-(2-iodobenzenesulfonamido)benzoic acid
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...
متن کاملElectrochemical Study of Iodide in the Presence of 2-Thiobarbituric Acid-Catalytic Determination of 2-Thiobarbituric Acid
Electrochemical oxidation of iodide has been studied in the presence of 2-thioborbituric acid using cyclic voltammetry and controlled-potential coulometry. The results indicate that, the resulting iodine takes part in halogenations reaction with 2-thiobarbituric acid. In addition, the present data are indicative of the suitability of iodide as a quasi mediator for determination of 2-thiobar...
متن کامل2-Methylamino-5-nitrobenzoic acid
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-(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.
