2-(4-Chlorophenyl)-4-[1-(4-chlorophenyl)-3-methyl-1H-pyrazol-5-yl]-5-methyl-1H-pyrazol-3(2H)-one

Abstract top

The title compound, C20H16Cl2N4O, has two molecules in the asymmetric unit. The two five-membered rings form a dihedral angle of 54.2 (3)° in one molecule and 56.8 (3)° in the other independent molecule. The amino group of the dihydropyrazolone unit of one molecule acts as a hydrogen-bond donor to the carbonyl group of the dihydropyrazolone system of the other molecule. The resulting N-H...O hydrogen bonds generate a chain running along the c axis. The crystal selected was a pseudo-merohedral twin with a 44.9 (3)% twin component.

Comment top

We are interested in studying the biological properties of derivatives of 1-phenyl-3-methyl-4(1-phenyl-3-methyl-1H-pyrazol-5-yl)-2H-3-pyrazolin-5-one. The crystal structure of the parent compound was reported in the context of understanding how amino as well as carbonyl groups connected to a π-system influence hydrogen bonding (Bertolasi et al., 1995; Kumar et al., 1995). The chloro-substituted compound (Scheme I, Fig. 1) crystallizes with two independant molecules in the asymmetric unit that display similar bond dimensions. Molecules are linked by N—H···O hydrogen bonds to generate a linear chain running along the c-axis of the monoclinic unit cell (Fig. 2).

The crystal studied is a racemic twin; the monoclinic unit cell, having a β-angle that is almost a right angle, emulates an orthorhombic unit cell.

Experimental top

1-[1-(4-Chlorophenyl)-3-methyl-5-oxo-4,5-dihydro-1H-pyrazol-4-yl]butane-1,3-dione (0.20 g, 0.7 mmol) and 4-chlorophenylhydrazine (0.20 g, 0.14 mmol) were heated in dimethoxyethane and dilute hydrochloric acid for 4 h (synthesis of the dione will be reported elsewhere.). The reaction was quenched by 1 M potassium carbonate. The aqueous layer was extracted with ethyl acetate. The combined organic phases were concentrated and the crude product recrystallized from dichloromethane to give 0.19 g of the title compound in 70% yield.

Refinement top

The refinement initially converged at an R index of about 20%. As the space group is not a centric space group, the structure was refined as a combination of general and racemic twinning, with the TWIN law of (-1 0 0 0 - 1 0 0 0 1) being used. The refinement on 3812 Friedel pairs gave a Flack parameter of 0.029; the portion of the twin component was 44.9%.

Carbon-bound H-atoms were placed in calculated positions (C—H 0.93 to 0.98 Å) and were included in the refinement in the riding model approximation, with U(H) set to 1.2 to 1.5U(C). Amino H-atoms were similarly generated.

Some of the diffraction spots of the second and third domain are quite close to those of the main domain affecting the refinement so that the ellipsoids of some atoms are observed to be significantly elongated. The anisotropic temperature factors of five carbon atoms (C1, C3, C10, C21 and C21) were therefore tightly restrained to be nearly isotropic. We have used a very tight restraint (ISOR 0.005). Even with ISOR 0.01, these atoms turn non-positive definite. Phenylene rings were restrained as rigid hexagons with carbon carbon bonds of 1.39 Å each.

A somewhat large WGHT was used that is almost the default value; the Goodness-of-Fit was not much different from the default value of 1.
