چکیده

In the crystal structure of the title compound, 2C(10)H(7)NO(4)·C(14)H(13)N(3)O(2), the two independent acid mol-ecules are connected through strong O-H⋯N and O-H⋯O hydrogen bonds to the central mol-ecule of the anti-tubercular drug N'-[(E)-4-meth-oxy-benzyl-idene]pyridine-4-carbohydrazide. Two such trimolecular units related by an inversion centre inter-act through a pair of N-H⋯O hydrogen bonds, forming a 3 + 3 mol-ecular aggregate. The dihedral angle between the aromatic rings of the hydrazone mol-ecule is 1.99 (12)°. The crystal packing features weak C-H⋯O and π-π stacking inter-actions, with centroid-centroid distances of 3.8460 (19) and 3.8703 (13) Å.

Crystal structure of 1H-imidazol-3-ium 2-(1,3-dioxoisoindolin-2-yl)acetate

The title salt, C3H5N2 (+)·C10H6NO4 (-), was obtained during a study of the co-crystallization of N'-[bis-(1H-imidazol-1-yl)methyl-ene]isonicotinohydrazide with (1,3-dioxoisoindolin-2-yl)acetic acid under aqueous conditions. The 1,3-dioxoisoindolinyl ring system of the anion is essentially planar [maximum deviation = 0.023 (2) Å]. In the crystal, cations and anions are linked via classical N-H⋯...

Synthesis, Characterization and Antimicrobial Activity of New 2-Phenylquinoline-4(3H)-one Derivatives

Quinazolinones is an important chemical synthesis with different physiological significance and pharmacological utility. Reaction of anthranilic acid with benzoyl chloride in pyridine yielded 2-phenyl4H-benzo[d][1,3]oxazin-4-one, which on condensation reaction with the tryptophan in glacial acetic acid afforded 3-(1H-indol-3-yl)-2-(4-oxo-2-phenylquinazolin-3(4H)-yl) propanoic acid (2).

The title compound, C(13)H(13)NO(4)S, the 1,3-dioxoisoindolin-2-yl unit is planar (r.m.s. deviation 0.0192 Å) and is oriented at a dihedral angle of 79.14 (18)° to the carboxyl-ate group. An intra-molecular C-H⋯O hydrogen bond leads to the formation of a planar (r.m.s. deviation 0.0419 Å)R(5) ring motif. In the crystal, mol-ecules are connected through O-H⋯O and C-H⋯O hydrogen bonds with R(2) (...
