2-Fluoro-4-(methoxycarbonyl)benzoic acid
In the crystal of the title compound, C(9)H(7)FO(4), classical carboxylate inversion dimers are linked by pairs of O-H⋯O hydrogen bonds. The packing is consolidated by C-H⋯F and C-H⋯O interactions. The benzene ring and the methoxycarbonyl group are nearly coplanar, with a dihedral angle of 1.5 (3)° between them, whereas the carboxyl group has a dihedral angle of 20.2 (4)° with respect to the be...
متن کامل6-Fluoro-4-oxochroman-2-carboxylic acid
The title compound, C(10)H(7)FO(4), is an inter-mediate in the synthesis of the drug Fidarestat, (2S,4S)-2-aminoformyl-6-fluoro-spiro[chroman-4,4'-imidazolidine]-2',5'-dione. The di-hydro-pyran-one ring adopts an envelope conformation with the asymmetric C atom in the flap position. In the crystal, the mol-ecules are linked into zigzag chains along [100] by O-H⋯O hydrogen bonds and C-H⋯π inter-...
متن کامل4-(3-Fluoro-4-methylanilino)-2-methylidene-4-oxobutanoic acid
The title compound, C12H12FNO3, crystallizes with two independent mol-ecules (A and B) in the asymmetric unit. The dihedral angle between the mean planes of the 3-fluoro-4-methyl-phenyl ring and the oxo-amine group is 25.7 (7)° in mol-ecule A and 71.3 (7)° in mol-ecule B, while the mean plane of the 2-methyl-idene-4-oxo-butanoic acid group is twisted by 76.2 (1)° from that of the oxo-amine grou...
متن کامل4′-Fluoro-2′-hydroxyacetophenone
The title compound, C(8)H(7)FO(2), crystallizes as discrete mol-ecules, the conformation of which may be influenced by an intra-molecular hydr-oxy-carbonyl O-H⋯O hydrogen bond.
متن کامل2-(2-Fluoro-4-nitrophenoxy)-3-nitropyridine
In the title compound, C11H6FN3O5, the dihedral angle between the aromatic rings is 72.4 (3)°. The NO2 groups form dihedral angles of 40.8 (2) and 4.8 (2)°, respectively, with the attached pyridine and benzene rings. The crystal structure features π-π stacking between centrosymmetrically related pairs of pyridine rings [centroid-centroid separation = 3.800 (3) Å].
