2-(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 ...
متن کامل1,3,7-Trimethyl-2,4-dioxo-1,2,3,4-tetrahydropteridine-6-carboxylic acid hemihydrate
In the title compound, C(10)H(10)N(4)O(4)·0.5H(2)O, the two rings of the pteridine system are nearly coplanar [dihedral angle = 4.25 (9)°]. The atoms of the carboxyl group are also coplanar with the pteridine unit [r.m.s. deviation from the mean plane of the pteridine skeleton = 0.092 (2) Å]. In the crystal, the presence of the water molecule of crystallization (O atom site symmetry 2) leads to...
متن کامل5-Methylisoxazole-4-carboxylic acid
In the title compound, C(5)H(5)NO(3), the mol-ecule lies on a crystallographic mirror plane with one half-mol-ecule in the asymmetric unit. An intramolecular C-H⋯O inter-action is present. In the crystal, strong inter-molecular O-H⋯N hydrogen bonds result in the formation of a linear chain structure along [100], and there are also weak C-H⋯O hydrogen bonds between the chains which help to stabi...
متن کامل5-Methyl-1-(3-nitrobenzyl)-1H-1,2,3-triazole-4-carboxylic acid monohydrate
The title compound, C(11)H(10)N(4)O(4)·H(2)O, was synthesized from 1-azido-methyl-3-nitro-benzene and ethyl acetyl-acetate. Single-crystal X-ray analysis reveals that the dihedral angle between the triazole and benzene ring planes is 84.80 (2)°. The packing of the mol-ecules is stabilized by strong O-H⋯O hydrogen bonds involving the solvent water mol-ecules as donors and acceptors. The resultin...
متن کامل1-Benzyl-5-methyl-1H-1,2,3-triazole-4-carboxylic acid monohydrate
In the title compound, C(11)H(11)N(3)O(2)·H(2)O, the planes of the triazole and phenyl rings are almost perpendicular to each other [dihedral angle 89.5 (3)°]. The crystal packing is stabilized by strong inter-molecular O-H⋯O and O-H⋯N hydrogen bonds involving the water mol-ecule as both donor and acceptor.
