In the title compound, C37H30N4O·C4H8O2, the dihedral angle between the pyrazole and dihydropyrazole rings is 74.09 (10)°. In the crystal, the components are linked into centrosymmetric tetramers (two main molecules and two solvent molecules) by C—H⋯O hydrogen bonds. C—H⋯π and π–π [shortest centroid-centroid separation = 3.6546 (9) Å] interactions are also observed.

A mixture of (E)-1-(biphenyl-4-yl)-3-(3-(4-methoxyphenyl)-1-phenyl-1 H-pyrazol-4-yl)prop-2-en-1-one (0.456 g, 1.0 mmol) and phenylhydrazine (0.162 g, 1.5 mmol) was refluxed in glacial acetic acid for 4 h. The mixture was then cooled to room temperature and resulting solid was filtered and dried to get title compound. Yield: 0.31 g, 56.77%. M.p.: 437–439 K. 1,4-Dioxane was used as crystallization solvent to yield colourless plates.
The H atoms were positioned geometrically [C–H = 0.95–0.99 Å] and refined using a riding model with Uiso(H) = 1.2 or 1.5 Ueq(C). A rotating group model was applied to the methyl group.

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. |

Pyrazolines are well-known and important nitrogen containing five-membered heterocyclic compounds with biological and pharmacological activities such as analgesic properties (Sahu et al., 2008). As part of our investigations of this area, we have synthesized the title compound to study its crystal structure (Fig. 1).
The solvent 1,4-dioxane ring (O2/O3/C39–C42) adopts a chair conformation (Cremer & Pople, 1975) with puckering parameters Q= 0.567 (2) Å, Θ= 179.0 (2)° and Φ= 302 (6)°. The ring A (N1/N2/C7/C14/C16), B (N3/N4/C17/C24/C25), C (C1–C6), D (C8–C13), E (C18–C23), F (C26–C31) and G (C32–C37) are essentially planar. The dihedral angle between the least-square planes of the rings are A/B = 74.09 (10)°, A/C = 42.50 (10)°, A/D = 8.04 (11)°, A/E = 86.29 (9)°, A/F = 77.25 (9)°, A/G = 83.37 (9)°, B/C = 55.81 (8)°, B/D = 74.18 (10)°, B/E = 19.64 (8)°, B/F = 3.18 (8)°, B/G = 30.67 (8)°, C/D = 49.32 (9)°, C/E = 71.40 (8)°, C/F = 57.94 (8)°, C/G = 86.47 (8)°, D/E = 86.48 (9)°, D/F = 77.36 (9)°, D/G = 86.35 (9)°, E/F = 16.50 (7)°, E/F = 20.45 (7)° and F/G = 28.72 (7)°.
The crystal structure is shown in Fig. 2. The molecules are linked into centrosymmetric tetramers (two main molecules and two solvent molecules) via C14—H14A···O2 and C41—H41B···O1 hydrogen bonds (Table 1). C—H···π interactions (Table 1) and π···π interactions of Cg2···Cg1 = 3.6546 (9) Å (symmetry code: x,y,z) and Cg2···Cg4 = 3.7773 (10) Å (symmetry code: 2-x,1-y,-z) further stabilized the crystal structure. [Cg1, Cg2 , Cg3, Cg4 and Cg5 are the centroids of the N1/N2/C7/C14/C16, N3/N4/C17/C24/C25, C1–C6, C26–C31 and C32–C37 rings, respectively].
