(Received 27 October 2008; accepted 28 October 2008; online 31 October 2008)

In the title compound, C24H20BrN3O4S, the central benzene ring makes dihedral angles of 17.13 (13), 39.83 (13) and 58.37 (13)°, respectively, with the pyrazolone ring, the bromo­benzene ring and the terminal phenyl ring. In the crystal structure, the packing is stabilized by a weak non-classical inter­molecular C—H⋯O hydrogen bond which links the mol­ecules into a chain propagating in [100].

Comment top

The synthesis and structure of Schiff bases have attracted much attention in biology and chemistry (Kahwa et al., 1986; Klayman et al., 1979). Many Schiff base derivatives have been synthesized and employed to develop protein and enzyme mimics (Santos et al., 2001). Among the large number of compounds, 4-amino-1,5-dimethyl-2-phenylpyrazol-3-one forms a variety of Schiff bases with aldehydes, and the synthesis and crystal structures of some of them, such as (E)-4-[(1,5-Dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-ylimino) methyl]-phenyl 4-chlorobenzoate (Han et al., 2007) has been reported.

As part of an investigation of the potential coordination properties of Schiff bases that could function as ligands, we now report the synthesis and structure of the title compound, (I).

In the title molecule (Fig. 1), the pyrazolone ring (C14—C16/N1/N2/N3/O4) is nearly planar, with an r.m.s. deviation for fitted atoms of 0.029 Å. It makes a dihedral angle of 50.07 (13)° with its attached phenyl ring (C19—C24). The central benzene ring (C7—C13/O3) is almost planar, with an r.m.s. deviation for fitted atoms of 0.040Å. This group makes dihedral angles of 17.13 (13)°, 39.83 (13)° and 58.37 (13)°, respectively, with the the pyrazolone ring (C14—C16/N1/N2/N3/O4), the terminal C1—C6 benzene ring and the terminal C19—C24 phenyl ring. Otherwise, all bond lengths and angles are within their normal ranges (Allen et al., 1987).

In the crystal, the packing is stabilized by a weak, non-classical intermolecular C17—H17A···O4 hydrogen bond that links molecules into one-dimensional extended chains running along the a axis (Table 1, Fig. 2).

Experimental top

An anhydrous ethanol solution (50 ml) of 4-formylphenyl 4-bromobenzenesulfonate (3.41 g, 10 mmol) was added to an anhydrous ethanol solution (50 ml) of 4-amino-1,5-dimethyl-2-phenylpyrazol-3-one (2.03 g, 10 mmol) and the mixture stirred at 350 K for 3 h under N2, giving a yellow precipitate. The product was isolated, recrystallized from acetonitrile, and then dried in a vacuum to give pure compound (I) in 87% yield. Yellow blocks of (I) were obtained by slow evaporation of an acetonitrile solution.

Refinement top

The H atoms were included in calculated positions (C—H = 0.93–0.96Å) and refined as riding with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(methyl C).

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 > 2σ(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.
