(Received 26 October 2010; accepted 28 October 2010; online 31 October 2010)

The crystal structure of the title compound, C15H12Cl2N2O2, contains three intramolecular hydrogen bonds; two C—H⋯O and a nonclassical N—H⋯Cl. The structure is further stabilized by intermolecular N—H⋯O hydrogen bonds and C—H⋯π interactions, resulting in a three-dimensional network. The two benzene rings make an interplanar angle of 58.0 (1)°.

Comment top

The amide moiety is an important constituent of many biologically significant compounds. As a part of studying the effect of substitutions on the structures of this class of compounds (Gowda et al., 2007; 2009; 2010), the crystal structure of N,N-bis(2-chlorophenyl)-malonamide has been determined (I) (Fig. 1).

The molecular structure of (I) includes three intermolecular hydrogen bonds (Table 1); two of them are C–H···O hydrogen bonds, the third is a non- classical N–H···Cl hydrogen bond. The two phenyl rings make an interplanar angle of 58.0 (1)°. The dihedral angle made by the two amido groups is 65.0 (2)°. The conformation of the ortho-chlorosubstituent is anti to the nearest carbonyl C=O bond, as indicated by the torsion angles, C2—C1—N1—C7 = -156.1 (2)° and C11—C10—N2—C9 = 137.2 (2)° in the first and the second phenyl rings, respectively. The chlorine Cl atom attached to the C1/C6 phenyl ring gives rise to a non conventional N–H···Cl hydrogen bond, with N–Cl distance of 2.9730 (18) Å and angle of 109°. The second chlorine atom, attached to the C10/C15 phenyl ring, makes a short intramolecular contact of 2.960 (2)Å with the nearest amide N atom, forming the N–H···Cl angle of 98°. In the crystal, the molecules are linked by intermolecular N–H···O hydrogen bonds into the chains running along the base vector [0 1 1] parallel to the bc-plane (Fig. 2). The chains are further stabilized by C–H···π interaction between the C3 atom of the C1/C6 ring and the centroid Cg2 of the phenyl ring C10/C15 at the position (-x, y + 1/2, -z + 1/2).

Experimental top

Malonic acid (0.3 mol) in dichloromethane (30 ml) was treated with 2-chloroaniline (0.6 mol) in dichloromethane (30 ml), dropwise with stirring. The resulting mixture was stirred for 3 hrs and kept aside for 12 hrs for the completion of reaction and evaporation of the solvent, dichloromethane. The product obtained was added to crushed ice to obtain the precipitate. The latter was thoroughly washed with water and then with saturated sodium bicarbonate solution and washed again with water. It was then given a wash with 2 N HCl. It was again washed with water, filtered, dried and recrystallized to the constant melting point from ethanol.

Block like colorless single crystals of the title compound used in X-ray diffraction studies were obtained by a slow evaporation of its ehanolic solution at room temperature.

Refinement top

All H atoms were positioned geometrically and refined using a riding model with C–H = 0.93 or 0.97 Å and N–H = 0.86 Å. The Uiso(H) values were set at 1.2Ueq(C, N).

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.
