6-Bromo-3-hydroxy-4-oxo-2-phenyl-4H-chromene-8-carboxylic acid dimethylformamide disolvate
In the title compound, C(16)H(9)BrO(5)·2C(3)H(7)NO, the chromene ring system is essentially planar. The two dimethyl-formamide solvent mol-ecules are linked by inter-molecular O-H⋯O hydrogen bonds to the 6-bromo-3-hydr-oxy-4-oxo-2-phenyl-4H-chromene-8-carboxylic acid molecules.
متن کامل3-Methyl-4-oxo-2-phenyl-4H-chromene-8-carboxylic acid
In the title compound, C(17)H(12)O(4), the chromene unit is approximately planar, the maximum deviation from the mean plane being 0.0166 Å. The attached phenyl ring makes a dihedral angle of 53.2 (1)° with the fused ring system. The packing of the mol-ecules in the crystal structure is governed by C-H⋯O and O-H⋯O hydrogen-bonding inter-actions.

In the mol-ecule of the title compound, C(10)H(9)N(3)O(2), the pyrazole ring is approximately coplanar with the amino and carboxyl groups. The phenyl group is twisted by 48.13 (3)° relative to this plane. An intra-molecular N-H⋯O hydrogen bond stabilizes the planar conformation of the mol-ecule. The mol-ecules are linked into two-dimensional sheets by two strong inter-molecular N-H⋯N and O-H⋯O ...
متن کامل5-Methyl-1-phenyl-1H-1,2,3-triazole-4-carboxylic acid
The title compound, C(10)H(9)N(3)O(2), was synthesized from azido-benzene and ethyl acetyl-acetate. A pair of hydrogen bonds [2.617 (2) Å] inter-connects a pair of the carboxyl groups, forming an R(2) (2)(8) inversion dimer, a frequent motif in carboxylic acids. In the title structure, the bonding H atom in the aforementioned O-H⋯O hydrogen bond is significantly shifted towards the acceptor O a...
متن کامل(2RS,8aRS)-6-Oxo-1,2,3,4,6,7,8,8a-octahydronaphthalene-2-carboxylic acid
The title racemate, C(11)H(14)O(3), aggregates in the crystal structure as acid-to-ketone O-H⋯O hydrogen-bonding catemers whose components are glide-related. The relative stereochemistry at the carboxyl group arises spontaneously during the synthesis. Two inter-molecular C-H⋯O=C close contacts were found, both involving the acid group.
