2-(Phenylsulfanyl)pyridine-3-carboxylic acid
The title compound, C(12)H(9)NO(2)S, belongs to the nitro-gen-containing group of heterocyclic organic compounds and crystallized with two mol-ecules per asymmetric unit. In the crystal, both molecules form inversion dimers linked by pairs of O-H-O hydrogen bonds. Weak symmetry-related C-H-O inter-actions link the carboxyl dimers along b axis. The dihedral angle between the two aromatic rings i...
متن کامل2-(Carboxymethylsulfanyl)pyridine-3-carboxylic acid monohydrate
The title compound, C(8)H(7)NO(4)S·H(2)O, was obtained by reaction of 2-mercaptopyridine-3-carboxylic acid with chloro-acetic acid. In the mol-ecular structure, the dihedral angle between the two least-squares planes defined by the pyridine ring and the carb-oxy group is 8.32 (9)°. The carboxy-methyl-sulfanyl group makes a torsion angle of 82.64 (12)° with the pyridine ring. An intra-molecular ...

The title compound, {[Cu(C(17)H(11)N(2)O(3))(2)(H(2)O)]·2H(2)O}(n), is a two-dimensional polymer. The Cu(2+) ion lies on the crystallographic twofold axis. The coordination sphere of the Cu(2+) ion can be described as a distorted square pyramid. All of the H atoms in the amide group and lattice water mol-ecules participate in O-H⋯O or N-H⋯O hydrogen bonding to strengthen the two-dimensioal fram...
متن کاملThe Synthesis of 2, 6 diamino- 3, 5-dinitropyridine from Direct Nitration Reaction of 2, 6 diamino pyridine in Different Temperature Conditions by Density Functional Theory
In this article, synthesis of the explosive 2, 6 (diamino) 3, 5 dinitro pyridine (ANPY) of the direct nitration reaction of 2, 6 diamino pyridine in different conditions of temperature, with density functional theory method were studied. For this purpose, at first the material contained in the both sides of reaction were geometrically optimized, then the calculation of the the...

In the title compound, [Cu(C(7)H(3)NO(4))(C(5)H(5)N)](n), the Cu(II) atom is in a slightly distorted octa-hedral coordination environment. Each Cu(II) atom is bound to two N atoms and one O atom of the pyridine-dicarboxyl-ate (PDA) ligand in a tridentate manner, one N atom of the pyridine mol-ecule and two bridging carboxyl-ate O atoms of adjacent PDA ligands, leading to a linear one-dimensiona...
