2-Chloroquinoline-3-carboxylic acid
The crystal structure of the title compound, C(10)H(6)ClNO(2), can be described by two types of crossed layers which are parallel to (110) and (10). The crystal packing is stabilized by inter-molecular C-H⋯O and O-H⋯N hydrogen bonds, resulting in the formation of a two-dimensional network and reinforcing the cohesion of the structure.
متن کامل1H-Pyrrole-2-carboxylic acid
In the title compound, C(5)H(5)NO(2), the pyrrole ring and its carboxyl substituent are close to coplanar, with a dihedral angle of 11.7 (3)° between the planes. In the crystal structure, adjacent mol-ecules are linked by pairs of O-H⋯O hydrogen bonds to form inversion dimers. Additional N-H⋯O hydrogen bonds link these dimers into chains extending along the a axis.
متن کامل2-Bromopyridine-3-carboxylic acid
The carboxylic acid residue in the title compound, C(6)H(4)BrNO(2), is twisted out of the plane of the other atoms, as indicated by the (Br)C-C-C-O(carbon-yl) torsion angle of -20.1 (9)°. In the crystal, supra-molecular chains mediated by O-H⋯N hydrogen bonds are formed with base vector [201] and C-H⋯O inter-actions reinforce the packing.
متن کاملSYNTHESIS OF 3-ARYLMETHYL-4- THIAZOLIDINE-CARBOXYLIC ACID-2-ONES AND 2-THIONES
Barium salts of dibenzylidene cystines 8a-c were obtained from the reaction of Lcystine with benzaldehyde or its derivatives in the presence of barium hydroxide. Their reduction with zinc and hydrochloric acid in methanol yielded the Narylmethylcysteines ?9a-c?. These can, in turn, be converted by esterification into the methyl esters ?10 a-c. ?Reaction of N, N'-carbonyl diimidazole (Im C...
متن کامل5-(Methoxycarbonyl)thiophene-2-carboxylic acid
In the title compound, C(7)H(6)O(4)S, a monoester derivative of 2,5-thio-phene-dicarboxylic acid, the carboxylic acid and the carboxylic acid ester groups are approximately coplanar with thio-phene ring, making a dihedral angle of 3.1 (4) and 3.6 (4)°, respectively. In the crystal structure, mol-ecules are connected by classical inter-molecular O-H⋯O hydrogen bonds, forming centrosymmetric dimers.
