4-Chlorophenyl 4-chlorobenzoate

B. T. Gowda, S. Foro, K. S. Babitha and H. Fuess

The structure of the title compound (4CP4CBA), C₁₃H₈Cl₂O₂, resembles those of 4-methylphenyl 4-chlorobenzoate (4MP4CBA), 4-chlorophenyl 4-methylbenzoate (4CP4MBA) and 4-methylphenyl 4-methylbenzoate (4MP4MBA), with similar bond parameters. The dihedral angle between the two benzene rings in 4CP4CBA is 47.98 (7)°, compared with 51.86 (4)° in 4MP4CBA, 63.89 (8)° in 4CP4MBA and 63.57 (5)° in 4MP4MBA. In the crystal structure, molecules are linked into helical chains running along the b axis by C-H-O hydrogen bonds.

Comment top

As part of a study of the substituent effects on the solid state structures of aryl benzoates (Gowda et al., 2007; Gowda, Foro et al., 2008; Gowda, Svoboda et al., 2008), the crystal structure of 4-chlorophenyl 4-chlorobenzoate (4CP4CBA) has been determined. The structure (Fig. 1) is similar to those of 4-methylphenyl 4-chlorobenzoate (4MP4CBA) (Gowda, Svoboda et al., 2008), 4-chlorophenyl 4-methylbenzoate (4CP4MBA) (Gowda, Foro et al., 2008) and 4-methylphenyl 4-methylbenzoate (4MP4MBA) (Gowda et al., 2007). The bond parameters in 4CP4CBA are similar to those in afore mentioned 4MP4CBA, 4CP4MBA, 4MP4MBA and other aryl benzoates (Gowda et al., 2007; Gowda, Foro et al., 2008; Gowda, Svoboda et al., 2008). The dihedral angle between the benzene and benzoyl rings in 4CP4CBA is 47.98 (7)°, compared to the values of 51.86 (4)° in 4MP4CBA, 63.89 (8)° in 4CP4MBA and 63.57 (5)° in 4MP4MBA.

In the crystal structure, the molecules are linked into helical chains (Fig. 2) running along the b axis by C—H—O hydrogen bonds (Table 1).

Experimental top

The title compound was prepared according to a literature method (Nayak & Gowda, 2008). The purity of the compound was checked by determining its melting point. It was characterized by recording its infrared and NMR spectra (Nayak & Gowda, 2008). Single crystals of the title compound used in X-ray diffraction studies were obtained by slow evaporation of its ethanol solution.

Special details top

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.
