N-(2-Chloro­phen­yl)succinamic acid

Abstract

The conformations of the N—H and C=O bonds in the amide segment of the structure of the title compound {systematic name: 3-[(2-chloro­phen­yl)amino­carbon­yl]propionic acid}, C10H10ClNO3, are trans to each other, while the conformation of the amide H atom is syn to the ortho-chloro group in the benzene ring. Further, the conformations of the amide O atom and the carbonyl O atom of the ester segment are also trans to the H atoms attached to the adjacent C atoms. In the crystal structure, mol­ecules are packed into infinite chains through inter­molecular N—H(...)O and O—H(...)O hydrogen bonds.

Comment

Amides are of interest as conjugation between the nitrogen lone pair electrons and the carbonyl pi-bond results in distinct physical and chemical properties. The amide moiety is also an important constituent of many biologically significant compounds. Thus, the structural studies of amides are of interest (Gowda, Kozisek et al., 2007 and references therein; Gowda, Svoboda et al., 2007; Gowda et al., 2008 and references therein); Jones et al., 1990; Wan et al., 2006). As a part of studying the effect of ring and side chain substitutions on the structures of this class of compounds, we have determined the crystal structure of N-(2-Chlorophenyl)-succinamic acid (N2CPMSA).

The conformations of N—H and C=O bonds in the amide segment of the structure are trans to each other, while the conformation of the amide hydrogen is syn to the ortho-chloro group in the benzene ring. Further, the conformations of the amide oxygen and the carbonyl oxygen of the ester segment are also trans to the H-atoms attached to the adjacent carbons (Fig. 1). The torsional angles of the groups, C1-N1-C7-C8, N1-C7-C8-C9, C7-C8-C9-C10 and C8-C9-C10-O2 in the side chain are 177.5 (2)°, 173.2 (2)°, 178.9 (2)° and 167.7 (2)°, respectively. The molecular packing in the structure via N—H···O and O—H···O intermolecular hydrogen bonds (Table 1) is shown in Fig.2.

Experimental

The solution of succinic anhydride (2.5 g) in toluene (25 ml) was treated dropwise with the solution of 2-chloroaniline (2.5 g) 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 completion of the reaction. The mixture was then treated with dilute hydrochloric acid to remove the unreacted 2-chloroaniline. The resultant solid N-(2-chlorophenyl)-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 ethanolic solution by slow evaporation at room temperature.

Refinement

The O-bound and N-bound H atoms were located in difference map, and later restrained to the distance O—H = 0.82 (2) Å, N—H = 0.86 (2) Å, respectivily. The other H atoms were positioned with idealized geometry using a riding model with C—H = 0.93–0.97 Å. All H atoms were refined with isotropic displacement parameters (set to 1.2 times of the Ueq of the parent atom).

Special details

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.
