In the title compound, C15H11NO4, the dihedral angle formed by the benzene ring and the essentially planar 2-benzofuran ring system is 55.93 (3)°. In the crystal, inter­molecular O—H⋯O hydrogen bonds link pairs of mol­ecules, generating centrosymmetric R22(8) ring motifs. These dimeric units are connected via N—H⋯O hydrogen bonds, forming C(6) chains along [100].

The molecular structure of the title compound is shown in Fig. 1. The dihedral angle formed by the benzene ring and the essentially planar isobenzofuran ring system is 55.93 (3)°. In the crystal, intermolecular O—H···O hydrogen bonds link pairs of molecules, generating centrosymmetric R22(8) ring motifs. These dimeric units are connected via N—H···O hydrogen bonds forming C(6) chains along [100] (see Fig. 2). The crystal structures of 2-(3-oxo-1,3-dihydroisobenzofuran-1-ylamino)benzoic acid (Odabaşoğlu & Büyükgüngör, 2008) and 3-(3-oxo-1,3-dihydroisobenzofuran-1-ylamino)benzoic (Li et al.(2009) have been published previously.

Experimental top

4-aminobenzoic acid (5.00 mmol) and 2-formylbenzoic acid (5.00 mmol) were added to an ethanol (35 ml) and DMF (15 ml) mix. The mixture was stirred at 353 K for 5 h. The resulting clear solution was evaporated under vacuum. The product was crystallized from a solution of DMF/methanol(1:1) yielding the title compound. Anal. yield: ca 98.6%. Single crystals suitable for X-ray analysis were obtained within one week by slow evaporation of a DMF/methanol (1:3) solution of the title compound.

Refinement top

All H atoms were placed in idealized positions (C—H = 0.93 or 0.98 Å, N—H = 0.88 Å and O—H = 0.86 Å), and constrained to ride on the atom to which they are bonded, and were included in the refinement in the riding-model approximation. Uiso(H) values were set equal to 1.5Ueq(parent atom) for carboxyl and the secondary amine H atom and to 1.2Ueq(parent atom) for all other H atoms.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
