In the title compound, C17H17ClN2O2·H2O, the dihedral angles formed by the aromatic rings of the chlorobenzene and methylbenzene groups with the mean planes of the attached NH–C(O)–CH2 fragments are 9.4 (4) and 62.9 (2)°, respectively. In the crystal, molecules are packed into layers parallel to the bc plane by O—H⋯O and N—H⋯O hydrogen-bond interactions.

Succinic anhydride (0.01 mol) in toluene (25 ml) was treated drop wise with o-toluidine (0.01 mol) in toluene (20 ml) with constant stirring. The resulting mixture was stirred for one hour and set aside for an additional hour at room temperature for completion of the reaction. The mixture was then treated with dilute hydrochloric acid to remove unreacted o-toluidine. The resultant solid N-(2-methylphenyl)succinamic acid was filtered under suction and washed thoroughly with water to remove the unreacted succinic anhydride and succinic acid. The compound was recrystallized to constant melting point from ethanol. The purity of the compound was checked by elemental analysis and characterized by its infrared and NMR spectra.
The N-(2-methylphenyl)succinamic acid obtained was then treated with phosphorous oxychloride and excess of 3-chloroaniline at room temperature with constant stirring. The resultant mixture was stirred for 4 h, kept aside for additional 6 h for completion of the reaction and poured slowly into crushed ice with constant stirring. It was kept aside for a day. The resultant solid, N-(3-chlorophenyl)-N'-(2-methylphenyl)succinamide monohydrate was filtered under suction, washed thoroughly with water, with a dilute sodium hydroxide solution and finally with water. It was recrystallized to constant melting point from an acetone/chloroform (1:1 v/v) solution. The purity of the compound was checked by elemental analysis, and characterized by its infrared and NMR spectra. Needle-like colourless single crystals used for the X-ray diffraction studies were grown by slow evaporation of an acetone/chloroform (1:1 v/v) solution at room temperature.
The amine and water H atoms were located in a difference Fourier map and refined with the N—H and O—H distances restrained to 0.86 (2) and 0.85 (2) Å, respectively. All other H atoms were positioned with idealized geometry using a riding model with the aromatic C—H = 0.93 Å, methyl C—H = 0.97 mÅ and methylene C—H = 0.97 Å, and with isotropic displacement parameters set to 1.2 times of the Ueq of the parent atoms. The crystals available for X-ray analysis were of rather poor quality and weak scatterers at high theta value, resulting in relatively high R values.

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. |

The amide and sulfonamide moieties are important constituents of many biologically important compounds. As a part of studying the substituent effects on the structures and other aspects of this class of compounds (Gowda & Kumar, 2003; Gowda et al., 2004; Saraswathi et al., 2011a,b), in the present work, the structure of N-(3-chlorophenyl)-N-(2-methylphenyl)-succinamide monohydrate is reported (Fig. 1). The conformations of the N—H and C═O bonds in the C—NH—C(O)—C—C—C(O)—NH—C fragment are anti to each other and the amide O atom is anti to the H atoms attached to the adjacent C atoms. Further, the conformations of the N—H bonds in the amide fragments are anti to the meta-chloro or the ortho-methyl groups in the respective adjacent benzene rings, similar to the anti conformations observed with respect to the ortho-methyl groups in N,N'-bis(2-methylphenyl)succinamide (II; Saraswathi et al., 2011a) and the meta-chloro groups in N,N'-bis(3-chlorophenyl)-succinamide (III; Saraswathi et al., 2011b).
The dihedral angle between the 3-chlorobenzene ring and the adjacent NH—C(O)—CH2 group is 9.4 (4)° and that between the 2-methylbenzene ring and the adjacent NH—C(O)—CH2 group is 62.9 (2)°, compared to the values of 62.1 (2)° for that between the benzene ring and the NH—C(O)—CH2 group in the two halves of (II), and 32.8 (1)° in (III)
The torsion angles C1—N1—C7—C8 and C11—N2—C10—C9 are -173.0 (6)° and -177.9 (6)°, in contrast to the value of 69.5 (7)° for the torsion angle C7—C8—C9—C10.
In the crystal packing, molecules are linked by N1—H1N···O3, N2—H2N···O2, O3—H31O···O2 and O3—H32O···O1 hydrogen bonds (Table 1; Fig. 2) to form layers parallel to the bc plane.
