In the 10H9Cl2NO3, the conformations of the amide O atom and the carbonyl O atom of the acid segment are anti to the H atoms of the adjacent –CH2 groups. The C=O and O—H bonds of the acid group are in relatively rare anti positions with respect to each other. This is an obvious consequence of the concerted effects of both the all-anti molecular conformation and the intermolecular hydrogen bond donated to the amide carbonyl group. In the crystal, molecules are packed into infinite chains through intermolecular N—H⋯O and O—H⋯O hydrogen bonds.

The solution of succinic anhydride (0.025 mol) in toluene (25 ml) was treated dropwise with the solution of 3,5-dichloroaniline (0.025 mol) also in toluene (20 ml) with constant stirring. The resulting mixture was stirred for about one hour and set aside for an additional hour at room temperature for the completion of reaction. The mixture was then treated with dilute hydrochloric acid to remove the unreacted 3,5-dichloroaniline. The resultant solid N-(3,5-dichlorophenyl)-succinamic acid was filtered under suction and washed thoroughly with water to remove the unreacted succinic anhydride and succinic acid. It 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 single crystals used in X-ray diffraction studies were grown in an ethanol solution by slow evaporation at room temperature.
The N-bound and O-bound H atoms were located in a difference map. The position of the N-bound H atom was refined with N—H = 0.95 (4) Å and that of the O—H was refined with a distance restrained to 0.82 (2) Å. The other H atoms were positioned with idealized geometry using a riding model [C—H = 0.93–0.97Å]. All H atoms were treated with isotropic displacement parameters (set to 1.2 times of the Ueq of the parent atom).

The amide moiety is an important constituent of many biologically significant compounds. As a part of studying the effect of ring and side chain substitutions on the structures of this class of compounds (Gowda et al., 2009), we have determined the crystal structure of N-(3,5-dichlorophenyl)-succinamic acid (N35DCPSA, systematic name: 3-[(3,5-dichloro)-aminocarbonyl]propionic acid). The conformations of N—H and C=O bonds in the amide segment of the structure are anti to each other and those of the amide O atom and the carbonyl O atom of the acid segment are also anti to the H atoms attached to the adjacent C atoms (Fig.1). Further, C=O and O—H bonds of the acid group are anti to each other, contrary to the more general syn conformation observed for C=O and O—H bonds of the acid group e.g. N-(2,6-dimethylphenyl)- succinamic acid (N26DMPSA, Gowda et al., 2009). The various modes of interlinking carboxylic acids by hydrogen bonds is described elsewhere (Leiserowitz, 1976). The packing of molecules involving dimeric hydrogen bonded association of each carboxyl group with a centrosymmetrically related neighbor has also been observed (Jagannathan et al., 1994). In the present study, the rare anti conformation of the C=O and O—H bonds of the acid group has been observed. The torsional angles of the groups, C2—C1—N1—C7, C6—C1—N1—C7, C1—N1—C7—C8, C1—N1—C7—O1, N1—C7—C8—C9, C7—C8—C9—C10, O1—C7—C8—C9, C8—C9—C10—O2 and C8—C9—C10—O3 in the side chain of N35DCPSA are -180.0 (3)°, -1.3 (4)°, -174.4 (3)°, 4.3 (5)°, 178.9 (2)°, -175.5 (2)°, 0.4 (2)°, 175.0 (3)° and -5.3 (5)°, respectively, compared to the corresponding values of 114.1 (2)°, -66.5 (2)°, -176.2 (1)°, 2.0 (3)°, -145.4 (2)°, -175.5 (1)°, 36.3 (2)°, -161.1 (2)° and 19.1 (3)°, respectively, for N26DMPSA. The N—H···O and O—H···O intermolecular hydrogen bonds pack the molecules into infinite chains in the structure (Table 1, Fig.2).
