Abstract
The asymmetric unit of the title co-crystal, C12H9N5O·C7H6O3, contains one molecule of N 6-benzoyladenine (BA) and one molecule of 4-hydroxybenzoic acid (HBA). The N 6-benzoyladenine (BA) has an N(7)—H tautomeric form with nonprotonated N-1 and N-3 atoms. This tautomeric form is stabilized by a typical intramolecular N—H⋯O hydrogen bond between the carbonyl (C=O) group and the N(7)—H hydrogen on the Hoogsteen face of the purine ring, forming a graph-set S(7) ring motif. The primary robust R 2 2(8) ring motif is formed in the Watson–Crick face via N—H⋯O and O—H⋯N hydrogen bonds (involving N1, N6—H and the carboxyl group of HBA). Weak interactions, such as, C—H⋯π and π–π are also observed in this crystal structure.
Chemical context
Adenine is one of the major nucleobases and some of its N
6-derivatives have plant hormone (kinetin) (Tr). They also offer a variety of hydrogen-bonding donor and acceptor sites (McHugh & Erxleben, 2011 ▸; Imaz et al., 2011 ▸). 4-Hydroxybenzoic acid is also a promising hydrogen-bond donor with the ability to form co-crystals with other organic molecules (Vishweshwar et al., 2003 ▸). It is used as an antimicrobial paraben (Barker & Frost, 2001 ▸). The present study investigates co-crystal formation between N
6- benzoyladenine and 4-hydroxybenzoic acid.
Structural commentary
In the title co-crystal (I), the asymmetric unit contains one N 6-benzoyladenine (BA) molecule and one 4-hydroxybenzoic acid (HBA) molecule (Fig. 1 ▸). The bond angle at N7 [C8—N7—C5 = 106.93 (17)°] is wider than at N9 [C8—N9—C4 = 104.19 (16)°]. In addition, the C8—N7 bond [1.343 (2)Å] is longer than C8—N9 [1.319 (3) Å]. These values agree with those reported earlier for the crystal structure of N 6-benzoyladenine (Raghunathan & Pattabhi, 1981 ▸). In the title co-crystal, the N 6-benzoyladenine also exists in the N(7)—H tautomeric form with non-protonated N1, N3 and N9 atoms. In the crystal structures of N 6-benzoyladenine (Raghunathan & Pattabhi, 1981 ▸), N 6-benzoyladenine-3-hydroxypyridinium-2-carboxylate (1:1) and N 6-benzoyl adenine-dl-tartaric acid (1:1) (Karthikeyan et al., 2015 ▸), N 6-benzoyladeninium nitrate (1:1) (Karthikeyan et al., 2016 ▸), N 6-benzoyl adenine–adipic acid (1:0.5) (Swinton Darious et al., 2016 ▸) and the title compound (I), the N 6-substituent is distal to the N1 and syn to the adenine nitrogen atom N7. This may be due to the participation of the N7 atom in N7—H7⋯O1A intramolecular hydrogen bond (Table 1 ▸) with an S(7) ring motif in the Hoogsteen face. In contrast, it may be noted that in the crystal structure of N 6-benzyladenine, (where no intramolecular hydrogen bond is present) the N 6-substituent is syn to N1 and distal to N7 and the adenine moiety exists in the N(9)—H tautomeric form (Raghunathan et al., 1983 ▸). The dihedral angle between the benzene ring and the carboxyl group of HBA is 1.5 (3)°, indicating that the benzene ring and the carboxyl group are nearly coplanar. A comparison of dihedral angles and the C6—N6—C10—C11 torsion angle reported for various N 6-benzoyladenine-containing crystal structures is given in Table 2 ▸.

Supramolecular features
The robust
(8) ring motif is formed in the Watson–Crick face (N1 and N6 atoms) via N—H⋯O and O—H⋯N hydrogen bonds involving the carboxyl group of HBA. The N7 atom is a bifurcated donor and the carbonyl oxygen atom acts as a double acceptor for the N—H⋯O hydrogen bonds. Inversion-related BA molecules form dimers through an array of hydrogen bonds, generating ring motifs, and these dimers are doubly bridged by inversion-related HBA molecules (Fig. 2 ▸). A large R
6
6(32) supramolecular ring is formed along the c-axis direction. A weak C8—H8⋯π interaction is also present. Further consolidation of the structure is provided by homo and hetero π–π stacking interactions [Cg1⋯Cg5(

Database survey
The neutral molecule N 6-benzoyladenine was first reported by Raghunathan & Pattabhi (1981 ▸). Various salts and co-crystals of N 6-benzoyladenine have also been reported: N 6-benzoyladenine–3-hydroxypyridinium-2-carboxylate (1:1) and N 6-benzoyladenine–dl-tartaric acid (1:1) (Karthikeyan et al., 2015 ▸), N 6-benzoyladeninium nitrate (1:1) (Karthikeyan et al., 2015 ▸), N 6-benzoyladenine–adipic acid (1:0.5) (Swinton Darious et al., 2016 ▸). Similarly, various co-crystals of HBA have been reported: 2-amino-4,6-dimethylpyrimidine–4-hydroxybenzoic acid (Balasubramani et al., 2006 ▸), 4-hydroxybenzoic acid–1H-imidazole (Wang et al., 2009 ▸), 2-amino-5-bromopyridine–4-hydroxybenzoic acid (Quah et al., 2010 ▸) and 4,6-dimethoxy-2-(methylsulfanyl)-pyrimidine–4-hydroxybenzoic acid (Thanigaimani et al., 2012 ▸).
Synthesis and crystallization
The title co-crystal was prepared by mixing a hot ethanol solution of N 6-benzoyladenine (30 mg) and 4-hydroxybenzoic acid (35 mg) in an equimolar ratio in a total volume of 30 mL. The mixture was warmed over a water bath for 30 min, filtered, and left aside for a few days. Colourless plate-shaped crystals were collected from the mother solution following slow cooling at room temperature.
Refinement details
Crystal data, data collection and structure refinement details are summarized in Table 3 ▸. Hydrogen atoms were readily located in difference-Fourier maps and were subsequently treated as riding atoms in geometrically idealized positions, with C—H = 0.93, N—H = 0.86 and O—H = 0.82 Å, and with U iso(H) = kU eq(C,N,O), where k = 1.5 for hydroxy and 1.2 for all other H atoms.

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