4-Aminoantipyrene, which contain pyrazolone ring, is an important compound in the class analgesic agent in otic solutions in combination with other analgesic such as benzocaine and phenylephrine. Pyrazolone is a five-membered lactam ring compound containing two N atoms and ketone in the same molecule. Lactam structure is an active nucleaus in pharmacological activity, especially in the class of nonsteroidal antiinflammatory agents used in the treatment of arthritis and other musculo skeletal and joint disorders. Pyrazolone derivatives, as lactam structure related compounds, are also widely used in preparing dyes and pigments. 4-aminoantipyrene and its derivatives have potential biological activities (Jain et al., 2003). Analgesic and antiinflammatory activities of the 4-aminoantipyrene complexes were extensively studied and reported (Filho et al., 1998; Sondhi et al., 1999). Apart from that, antimicrobial and anticancer activity of the 4-aminoantipyrine derivatives and their metal complexes caught the attention of many researchers during last decade (Mishra, 1999; Sondhi et al., 2001). As intra- and intermolecular hydrogen bonding interactions play a key role in bio-molecular interactions we are interested on the structural elucidation of potentially bioactive compounds and their hydrogen bonding interactions in different environments. Thus, we are concerned with the biomolecular hydrogen bonding interactions through their X-ray analyses of crystalline complexes involving drugs and vitamins with inorganic and organic acids (Athimoolam & Rajaram, 2005; Athimoolam & Natarajan, 2006a-c).

Intermolecular forces also play very essential role in the formation of supramolecular organic systems. The phenomenon of hydrogen bonding enlightens the area of molecular recognition, crystal-engineering research and organic synthons for supramolecular research (Desiraju, 1989). Carboxylic acids and amines are two commonly used functional groups in crystal engineering because they generally form robust architectures via O—H···O and N—H···O hydrogen-bonded interactions (Etter et al., 1990). 4-aminoantipyrene is one of the such important ligands since it has potential sites for hydrogen bonding interactions, viz., the amine N atom (as donor) and carbonyl O atom (as acceptor). Consideration of these above specifics and to study the supramolecular geometry through hydrogen bonding extensions, the present investigation was undertaken. 4-aminoantipyrene was treated with salicylic acid and the title compound is crystallized.

The asymmetric unit of (I) consists of one single charged protonated 4-aminoantipyrene cation and a deprotonated salicylate anion (Fig 1). Interatomic distances and angles are normal and in good agreement with the similar structures (Allen, 2002). The expected proton transfer from salicylic acid to 4-aminoantipyrene is established at N5 atom. The protonation on the N site of the cation is evidenced from the elongated C—N bond distance and the deprotonation on anion is confirmed from the COO^- symmetric bond distances (Table 1). The phenyl ring of the cation is oriented with an angle of 67.0 (1)° to the five membered pyrazolone ring. Also, in the asymmeric unit, the phenyl ring of the cation is making a dihedral angle of 87.5 (1)° with the phenyl ring of the anion. The carboxylate plane of the salicylate anion is twisted from the plane of the aromatic ring with an angle of 13.7 (3)°. The twisting of carboxylate plane can be associated with the hydrogen bonding interactions of amino group of the cation. Due to the packing specificity of the crystal, one of the methyl atoms (C22) of the cation is slightly out of plane of the five-membered pyrzalone ring with the distance of 0.542 (3) Å.

The most elegant aspect of the present work is found not only in the molecular structure but also in the crystal packing via N—H···O and O—H···O hydrogen bonds. Fig. 2 shows the aggregation of the molecules around the inversion centres of the unit cell through ring motifs. As a characterestic H-bond, salicylate anion consists a self associated intramolecular S(6) motif through O—H···O hydrogen bond. The amino group of the cation is involved in two two-centered and one three-centered hydrogen bonds. The amino and carbonyl O atom of the cation is involving in N—H···O hydrogen bond which leads to a classical molecular dimerization through the ring R₂²(10) motif around the inversion center of the unit cell (Fig. 3). Other two H atoms of amino group are involved in N—H···O hydrogen bonds with the adjascent salicylate anions. This leads to another ring R₄²(8) motif formed through two cations and two anions (Fig. 4). This ring motif is further accompanied with another adajascent ring R₁²(4) motif through the bifuracted (two-centered) hydrogen bond. These three intermolecular ring motifs are intersected and extending along the a axis of the unit cell. This leads to hydrophilic region at the plane y=1/2 which are sanwitched between the hydrophobic regions at y=1/4 and 3/4.

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.
