4′-Hydroxybiphenyl-4-carboxylic acid
The title compound, C(13)H(10)O(3), has potential oxygen donor and acceptor sites. Inter-molecular hydrogen bonding between neighboring carboxyl-ate groups leads to the formation of hydrogen-bonded dimers [graph-set motif R(2) (2)(8)]. A second hydrogen-bonding inter-action between the hydr-oxy groups generates a chain and extends the structure into a lamellar layer. One of the benzene rings is...
متن کامل4-[(4-Bromophenyl)amino]-2-methylidene-4-oxobutanoic acid
In the title compound, C11H10BrNO3, two independent mol-ecules (A and B) crystallize in the asymmetric unit. The dihedral angles between the mean planes of the 4-bromo-phenyl ring and amide group are 24.8 (7) in mol-ecule A and 77.1 (6)° in mol-ecule B. The mean plane of the methyl-idene group is further inclined by 75.6 (4) in mol-ecule A and 72.5 (6)° in mol-ecule B from that of the amide gro...
متن کامل4-[(4-Acetylphenyl)amino]-2-methylidene-4-oxobutanoic acid
In the title compound, C13H13NO4, the N-C(=O) bond length of 1.354 (2) Å is indicative of amide-type resonance. The dihedral angle between the mean planes of the benzene ring and oxo-amine group is 36.4 (3)°, while the mean plane of the 2-methyl-idene group is inclined by 84.2 (01)° from that of the oxo-amine group. In the crystal, classical O-H⋯O hydrogen bonds formed by the carb-oxy-lic acid ...
متن کامل4-[(E)-(4-Fluorobenzylidene)amino]benzoic acid
In the title compound, C(14)H(10)FNO(2), the benzene rings make a dihedral angle of 57.50 (13)°, and the molecule has an E configuration about the C=N bond. In the crystal, molecules are linked via pairs of O-H⋯O hydrogen bonds, forming inversion dimers.
متن کامل4-[(2-Fluorophenyl)amino]-4-oxobutanoic acid
The crystal structure of the title compound, C(10)H(10)FNO(3), contains dimers of the asymmetric unit, with R(2) (2)(8) rings arising from inter-molecular O-H⋯O hydrogen bonding through the carboxyl-ate groups. Adjacent dimeric units are connected to each other through one N-H⋯O and two C-H⋯O inter-molecular hydrogen bonds. C-H⋯O hydrogen bonds involving the aromatic ring and the O atoms of two...
