In the title compound, C26H19ClN2O, the 2-chlorophenyl group forms dihedral angles of 59.6 (1) and 31.9 (1)° with the phenyl rings. The two phenyl rings are inclined at a dihedral angle of 32.9 (1)° with respect to each other. In the crystal, an intermolecular C—H⋯N hydrogen bond links the molecules into a polymeric chain running along the c axis.

The title compound was prepared by the reaction of 2-(1-phenylethylidene)malononitrile (0.168 g, 1.0 mmol) and 1-phenyl-3-(2-chlorophenyl)propen-1-one (0.242 g, 1.0 mmol) in water (10 ml) at reflux for 14 h (yield 82%, mp. 438–439 K). Crystals of the title compound suitable for X-ray diffraction were obtained by slow evaporation of a dimethylformamide solution.
The H atoms were calculated geometrically and refined as riding, with C—H = 0.93–0.98 Å, and with Uiso(H) = 1.2Ueq(parent atom).
There has been a growing recognition that water has become an attractive medium for many organic reactions (Breslow, 1991). Recently, we have demonstrated the Michal
between 2-(1-phenylethylidene)malononitrile and 1-phenyl-3-(2-chlorophenyl)propen-1-one in water without a catalyst and synthesized the title compound which is reported in this article.In the title compound (Fig. 1), 2-chlorophenyl group forms dihedral angles of 59.6 (1) and 31.9 (1) ° with benzene rings (C1—C6) and (C15—C20), respectively. The two benzene rings are inclined with respect to each other at a dihedral angle of 32.9 (1) °. There is an intermolecular hydrogen bond C8—H8A···N1 (Table 1) resulting in a polymeric chain along the c-axis. In addition, two intramolecular interactions further stabilize the structure (Fig. 2).

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. |

There has been a growing recognition that water has become an attractive medium for many organic reactions (Breslow, 1991). Recently, we have demonstrated the Michal addition reaction between 2-(1-phenylethylidene)malononitrile and 1-phenyl-3-(2-chlorophenyl)propen-1-one in water without a catalyst and synthesized the title compound which is reported in this article.
In the title compound (Fig. 1), 2-chlorophenyl group forms dihedral angles of 59.6 (1) and 31.9 (1) ° with benzene rings (C1—C6) and (C15—C20), respectively. The two benzene rings are inclined with respect to each other at a dihedral angle of 32.9 (1) °. There is an intermolecular hydrogen bond C8—H8A···N1 (Table 1) resulting in a polymeric chain along the c-axis. In addition, two intramolecular interactions further stabilize the structure (Fig. 2).
