2-Phenyl-1,3-selenazole-4-carboxylic acid
In the title compound, C(10)H(7)NO(2)Se, the two rings are twisted, making a dihedral angle of 12.42 (9)°. In the crystal, pairs of mol-ecules are disposed about an inversion center, generating O-H⋯O hydrogen-bonded dimers.
متن کامل5-Amino-1-phenyl-1H-pyrazole-4-carboxylic acid
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 کاملTris(1,10-phenanthroline-κ2 N,N′)zinc(II) chloride 2-phenyl-4-selenazole-5-carboxylate decahydrate
The asymmetric unit of the title salt, [Zn(C(12)H(8)N(2))(3)](C(10)H(6)NO(2)Se)Cl·10H(2)O, contains a [Zn(phen)(3)](2+) cation (phen is 1,10-phenanthroline), uncoordinated chloride and 2-phenyl-4-selenazole-5-carboxyl-ate anions and ten uncoord-in-ated water mol-ecules. The central Zn(II) ion is six-coordinated by six N atoms from three phen ligands in a distorted octa-hedral geometry. An exten...
متن کاملDesign, Synthesis and Antibacterial Evaluation of Some New 2-Phenyl-quinoline-4-carboxylic Acid Derivatives.
A series of new 2-phenyl-quinoline-4-carboxylic acid derivatives was synthesized starting from aniline, 2-nitrobenzaldehyde, pyruvic acid followed by Doebner reaction, amidation, reduction, acylation and amination. All of the newly-synthesized compounds were characterized by ¹H-NMR, (13)C-NMR and HRMS. The antibacterial activities of these compounds against Gram-negative (Escherichia coli, Pseu...
