Abstract

The asymmetric unit of the title co-crystal, C₁₂H₉N₅O·0.5C₆H₁₀O₄, consists of one molecule of N ⁶-benzoyladenine (BA) and one half-molecule of adipic acid (AA), the other half being generated by inversion symmetry. The dihedral angle between the adenine and phenyl ring planes is 26.71 (7)°. The N ⁶-benzoyladenine molecule crystallizes in the N(7)—H tautomeric form with three non-protonated N atoms. This tautomeric form is stabilized by intramolecular N—H⋯O hydrogen bonding between the carbonyl (C=O) group and the N(7)—H hydrogen atom on the Hoogsteen face of the purine ring, forming an S(7) ring motif. The two carboxyl groups of adipic acid interact with the Watson–Crick face of the BA molecules through O—H⋯N and N—H⋯O hydrogen bonds, generating an R ₂ ²(8) ring motif. The latter units are linked by N—H⋯N hydrogen bonds, forming layers parallel to (10-5). A weak C—H⋯O hydrogen bond is also present, linking adipic acid molecules in neighbouring layers, enclosing R ² ₂(10) ring motifs and forming a three-dimensional structure. C=O⋯π and C—H⋯π interactions are also present in the structure.

Chemical context

Adipic acid has been widely used in controlled-release formulations of many drugs and food additives (Roew et al., 2009 ▸). N ⁶-benzoyladenine is a synthetic analogue of a group of naturally occurring N ⁶-substituted adenines having plant-growth-stimulating activity (cytokinins) (McHugh & Erxleben, 2011 ▸). A number of co-crystals involving adipic acid have been reported in the literature (Lemmerer et al., 2012 ▸; Lin et al., 2012 ▸; Matulková et al., 2014 ▸; Thanigaimani et al., 2012 ▸). This paper deals with a co-crystal formed between N ⁶-benzoyladenine and adipic acid (I).

Structural commentary

The asymmetric unit of (I) contains one N ⁶-benzoyladenine (BA) molecule and a half-molecule of adipic acid (AA). As evident from the angles at N7 [C8—N7—C5 = 106.82 (11)°] and N9 [C8—N9—C4 = 103.90 (11)°], the N ⁶-benzoyladenine moiety exists in the N(7)—H tautomeric form with non-protonated N1, N3 and N9 atoms. In addition, the C8—N7 bond [1.3415 (17) Å)] is longer than C8—N9 [1.3175 (19) Å]. These values are similar to those in neutral N ⁶-benzoyladenine (Raghunathan & Pattabhi, 1981 ▸). An intramolecular hydrogen bond in the Hoogsteen face between N7—H7 and the benzoyl oxygen atom O1 forms a S(7) ring motif. The dihedral angle between the adenine and phenyl ring plane is 26.71 (7)° and the C6—N6—C10—C11 torsion angle is 173.08 (14)°. The bond lengths and bond angles of AA are in the range of values reported (Srinivasa Gopalan et al., 1999 ▸; 2000 ▸). The values for the torsion angles C18—C19—C19a—C18a [180.00 (13)°] and C17—C18—C19—C19a [–176.09 (14)°] indicate that the carbon chain of AA is fully extended.

In the crystal structures of N ⁶-benzyladenine (Raghunathan & Pattabhi, 1981 ▸), N ⁶-furfuryladenine (Soriano-Garcia & Parthasarathy, 1977 ▸), N ⁶-benzyladenine hydrobromide (Umadevi et al., 2001 ▸), N ⁶-furfuryladenine hydrochloride (Stanley et al., 2003 ▸), N ⁶-benzyladeninium p-toluenesulfonate (Tamilselvi & Muthiah, 2011 ▸), N ⁶-benzyladeninium nitrate, N ⁶-benzyladeninium 3-hydroxy picolinate (Nirmalram et al., 2011 ▸) and the hydrate adduct of N ⁶-benzyladenine-5-sulfosalicylic acid (Xia et al., 2010 ▸), the N ⁶-substituent is distal to the N7 position, whereas in the crystal structures of N ⁶-benzoyladenine (Raghunathan et al., 1983 ▸), N ⁶-benzoyladenine-3-hydroxypyridinium-2-carboxylate (1:1), N ⁶-benzoyladenine-dl-tartaric acid (1:1) (Karthikeyan et al., 2015 ▸), N ⁶-benzoyladeninium nitrate (Karthikeyan et al., 2015 ▸) and the title compound, the N ⁶-substituent is distal to N1 and syn to adenine nitrogen atom N7. In the present structure, this may be attributed to the presence of the N7—H7⋯O1A intramolecular hydrogen bond (Table 1 ▸).

Supramolecular features

Each of the two carboxyl groups of adipic acid interacts with the Watson–Crick face (atoms N1 and N6) of the corresponding BA through O—H⋯N and N—H⋯O hydrogen bonds, generating an Inline graphic (8) ring motif (Fig. 1 ▸). Thus each adipic acid molecule bridges two BA molecules. The latter units are linked by N7—H7⋯N9ⁱⁱⁱ hydrogen bonds (Table 1 ▸) forming layers parallel to plane (10). A weak C—H⋯O hydrogen bond (C19—H19B⋯O3A ^iv) is also present (Table 1 ▸ and Fig. 2 ▸), linking adipic acid molecules in neighbouring layers, enclosing Inline graphic (10) ring motifs and forming a three-dimensional structure. Thus atom O3A functions as a bifurcated hydrogen-bond acceptor whereas N7—H is a bifurcated hydrogen-bond donor.

Database survey

The neutral molecule N ⁶-benzoyladenine was reported by Raghunathan & Pattabhi (1981 ▸). Co-crystals have also been reported: N ⁶-benzoyladenine-3-hydroxypyridinium-2-carboxylate (1:1), N ⁶-benzoyladenine-dl-tartaric acid (1:1) (Karthikeyan et al., 2015 ▸) and N ⁶-benzoyladeninium nitrate (Karthikeyan et al., 2016 ▸). Similarly, co-crystals of adipic acid with pyrimidine derivatives [adenine (Byres et al., 2009 ▸), caffeine (Bučar et al., 2007 ▸), cytosine (Das & Baruah, 2011 ▸), bis-pyrimidine-amine-linked xylene spacer (Goswami et al., 2010 ▸)] have also been reported.

Synthesis and crystallization

The title co-crystal was synthesized by mixing a DMF solution of N ⁶-benzoyladenine (30 mg) and adipic acid (19 mg) (total volume = 10 mL). The mixture was warmed in a water bath for 20 min. After cooling to room temperature, colourless plate-like crystals were collected from the mother liquor after a few days (m.p. 438 K).

Refinement

Crystal data, data collection and structure refinement details are summarized in Table 2 ▸. Atoms O1 and O3 are disordered over two positions with refined occupancy ratios of 0.57 (3):0.43 (3) and 0.63 (3):0.37 (3), respectively. 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 (aromatic) or 0.97 (methylene), 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.
