(Received 24 February 2013; accepted 30 April 2013; online 4 May 2013)

In the title compound, C₂₈H₂₄F₆N₂O₃, the mean plane of the central pyrazoline ring forms dihedral angles of 2.08 (9) and 69.02 (16)° with the 2-benzyloxy-6-hydroxy-4-methylphenyl and 3,5-bis(trifluoromethyl)phenyl rings, respectively. The dihedral angle between the mean planes of the pyrazoline and 3,5-bis(trifluoromethyl)phenyl rings is 68.97 (9)°. An intramolecular O—H⋯N hydrogen bond is observed, which forms an S(6) graph-set motif. In the crystal, pairs of weak C—H⋯F halogen interactions link the molecules into inversion dimers while molecular chains along [100] are formed by C—H⋯O contacts.

Comment top

Pyrazoline derivatives, prominent nitrogen containing heterocyclic compounds, play an important role in medicinal chemistry. These derivatives are found to possess antidepressant, antioxidant, anti- inflammatory (Smith et al., 2001), anticonvulsant, antimicrobial, antiviral, monoamine oxidase (MAO-A and MAO-B) inhibitor, and anticancer activity. Our on-going research is focused on the synthesis and crystal structures of related pyrazoline derivatives of these types of heterocyclic compounds (Patel et al. 2007, Patel et al. 2012). We report here the synthesis and crystal structure of the title compound, C₂₈H₂₄N₂O₃F₆, (I).

In (I), propionaldehyde, 3-benzyloxy-5-methyl-phenol and 1,3-bis-trifluro methyl benzene are bonded to N1, C3 and C5 of the pyrazoline ring, respectively. The dihedral angles between the mean planes of the pyrazoline ring and the 3-benzyloxy-5-methyl-phenol (C10—C15) and 1,3-bis-trifluro methyl benzene rings (C26—C31) are 2.03 (15)° and 69.02 (16)° respectively. An intra-molecular O16—H16···N2 hydrogen bond (Fig.1) forms an S1,1(6) graph set motif configuration (Bernstein et al., 1995). The mean plane of the propionaldehyde group (C6—C8/O9) is inclined by 12.56 (13)° to the meam plane of the pyrazoline ring. Weak C—H···F Halogen intermolecular interactions are observed that form inversion dimers (Fig. 2).

1-[2-benzyloxy-6-hydroxy-4-methyl phenyl]-3-(3, 5-bis (trifluoromethyl) phenyl)prop-2-en-1-one (5 g m, 0.01 mole), hydrazine hydrate (0.70 g m, 0.014 mole) and butanoic acid (20 ml) were heated to 115–120 °C for 4 h. The resulting solution was concentrated and allowed to cool and then poured into ice. The resulting solid was filtered, washed with water, dried and rystallized from methanol as pale yellow needles.

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.
