(Received 31 May 2010; accepted 3 June 2010; online 9 June 2010)

The title Schiff base compound, C23H23N5O, was synthesized by the reaction of 4-amino­phenazone and 3,5-dimethyl-1-phenyl­pyrazole-4-carbaxaldehyde. The mol­ecule adopts an E configuration about the central C=N double bond. A weak intra­molecular C—H⋯O hydrogen bond generates an S(6) ring motif. The dihedral angle between the pyrazole rings is 24.72 (10)° and the dihedral angles between the pyrazole rings and the adjacent phenyl rings are 58.67 (10) and 46.58 (11)°. The crystal structure is stabilized by weak C—H⋯π inter­actions involving the pyrazolone and phenyl rings.

Heterocyclic Schiff bases have attracted continuing interest over the years because of their varied biological activities (Nawaz et al., 2009). Recently they have found application in drug development for the treatment of allergies (Li et al., 1999), hypertension (Urena et al., 2003), inflammation (Geronikaki et al., 20003), bacterial (Shanker et al., 2009), HIV infections (Pandeya et al., 1999) and hypnotics (Sridhar et al., 2002). More recently they have also been used for the treatment of pain acting as fibrinogen receptor antagonists with antithrombotic activity (Nawrocka et al., 2004). Due to wide application of pyrazoline-containing Schiff bases, we have synthesized a novel pyrazoline-containing Schiff base from 4-aminophenazone.

In the title compound (Fig. 1), the rings A (C14–C19), B (N4/N5/C11–C13), C (N1/N2/C7–C9) and D (C1–C6) are essentially planar. The dihedral angle between the best planes of the rings are A/B = 58.67 (10)°, A/C = 83.07 (10)°, A/D = 79.53 (12)°, B/C = 24.72 (10)°, B/D = 44.68 (11)° and C/D = 46.58 (11)°. The molecule adopts a trans configuration about the central C10N3 double bond. The C–N bond lengths of N1–C6 = 1.423 (2) Å; N2–C8 = 1.375 (2) Å; N3–C9 = 1.400 (2) Å; N5–C13 = 1.357 (2) Å; N1–C7 = 1.404 (2) Å; N2–C20 = 1.467 (2) Å; N4–C12 = 1.325 (2) Å and N5–C14 = 1.429 (2) are normal for C–N single-bond distances. The distance between C10–N3 (1.287 (2) Å) is typical for a CN double-bond distance. These bonds are comparable with those in N-(1H-benzoimidazol-2-ylmethyl)-N-(2,6-dichlorophenyl) amine (Eryigit & Kendi, 1998). The N1–N2 and N4–N5 (1.4082 (19) Å & 1.3702 (19) Å) single-bond lengths are comparable with those in 2,6-bis(3,5-dimethylpyrazol-1-ylmethyl) pyridine (Manikandan et al., 2000). An weak intramolecular C10—H10A···O1 hydrogen bond interaction generates an S(6) ring motif (Bernstein et al., 1995).

In the crystal structure (Fig. 2) there are no classical hydrogen bonds but stabilization is provided by weak C20—H20C···Cg1i, C19—H19A···Cg2ii and C22—H22B···Cg2iii interactions (see Table 1 for symmetry codes). Cg1 and Cg2 are the centroids of rings (N4/N5/C11–C13) and (C1–C6) rings respectively.

Experimental top

A mixture of 4-aminophenazone (0.50g, 0.0025 mol) and 3,5-dimethyl-1- phenylpyrazole-4-carbaxaldehyde (0.50 g, 0.0025 mol) in methanol (15 mL) was heated for 3 h to give a yellow precipitate. It was then filtered and washed with methanol to gives the pure schiff bases ( I). Colourless crystals of (I) are recrystallized from methanol. Yield: 68%; m. p. 206°C. IR (KBr) νmax cm-1: 2980 (C–H aromatic), 1642 (HCN), 1607 (CO), 1134 (C–N). 1H-NMR (600 MHz, CDCl3) d: 9.75 (CHN, s), 7.49–7.29 (CH aromatic, m), 3.1(N–CH3, s), 2.84 (N-CH3, s), 2.15 (CH3, s), 1.70 (CH3, s).

Refinement top

Atoms H1A, H2A, H3A, H4A, H5A, H10A, H15A, H16A, H17A, H18A and H19A were located from a difference Fourier maps and refined freely. The methyl H atoms were positioned geometrically [C–H = 0.96 Å] and were refined using a riding model, with Uiso(H) = 1.5Ueq(C). A rotating group model was used for the methyl group.

Special details top

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.

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 > 2sigma(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.
