In the title 3:1 adduct, 3C7H6O3·C5H5N5, an intramolecular O—H⋯O hydrogen bond occurs in each of the three 2-hydroxybenzoic acid molecules. In the crystal, the components are linked by N—H⋯O and O—H⋯N hydrogen bonds.

Adenine 1.35 g(0.01 mol) and 2-hydroxybenzoic acid 4.14 g(0.03 mol) with ethanol were stirred for 18 h at 353 K. The solution was then filtered and concentrated to afford the white title compound 3.63 g (yield 70%). Colourless blocks of (I) were obtained by slow evaporation of an ethanol-water (10:1 v/v) solution at room temperature over a period of one week.
The H atoms were located geometrically (C—H = 0.93–0.97 Å, N—H = 0.86Å, O—H = 0.82Å) and refined as riding with Uiso(H) = 1.2 Ueq(carrier). The highest difference peak is 0.45Å from H6A and might indicate unmodelled positional disorder of O1.

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. |

Adenine and its derivatives are an important class of compounds because they exhibit better pharmacological activities such as penicillins,antibiotics (Forsythe & Ennis, 1999). We report here the synthesis and structure of the title compound, (I) (Fig. 1), as part of our ongoing studies on new adenine compounds with higher bioactivity.
The adenine ring system is essentially planar, with a dihedral angle of 0.37 (8) between the ring (atoms N4/N5/C24—C26) and the ring (N2/N3/C22—C25). The dihedral angles between the mean planes of the adenine system and rings (C1—C6) and rings (C8—C13) and rings (C15—C20) are 2.41 (7) and 85.83 (7)and 80.3 (7), respectively. The dihedral angle between rings(C1—C6) and rings (C8—C13) is 84.02 (8). In the crystal structure, weak inter molecular C—H···O hydrogen bonds and intramolecular O—H···O hydrogen-bond interactions to stabilize the crystal structure (Table 1). The packing (Fig.2) is further stabilized by weak O—H···O interactions.
