(Received 21 February 2012; accepted 22 February 2012; online 29 February 2012)

In the mol­ecule of the title compound, C10H7ClN2O5, the acyclic C=C double bond is cis configured. The C=O and O—H bonds of the acid group are in a relatively rare anti position to each other, due to the donation of intramolecular hydrogen bond to the amide by the carboxyl group. The nitro group is significantly twisted [dihedral angle = 66.9 (3)°] out of the plane of the remaining atoms, which are almost coplanar (r.m.s. deviation for non-H atoms except the nitro group = 0.202 Å). In the crystal, N—H⋯O hydrogen bonds link the mol­ecules into zigzag chains running along the b axis.

As part of our studies on the substituent effects on the structures and other aspects of N-(aryl)-amides (Gowda et al., 2000, 2003; Chaithanya et al., 2012), N-(aryl)-methanesulfonamides (Gowda et al., 2007); N-chloroarylsulfonamides (Jyothi & Gowda, 2004) and N-bromoarylsulfonamides (Usha & Gowda, 2006), in the present work, the crystal structure of N-(4-Chloro-3-nitrophenyl)maleamic acid has been determined (Fig. 1). The conformations of the N—H and the CO bonds in the amide segment are anti to each other. The N—H bond is also anti to the meta–nitro group. Further, the conformation of the amide CO is anti to the H atom on the adjacent –CH group, while the carboxyl CO of the acid segment is syn to the adjacent –CH group. Furthermore, the CO and O—H bond of the acid group are in relatively rare anti position to each other, due to the donation of hydrogen bond to the amide by the carboxyl group, similar to that observed in N-(3-Chloro-4-methylphenyl)maleamic acid (I) (Chaithanya et al., 2012).

The dihedral angle between the phenyl ring and the amide group in the title compound is 11.52 (27)°, compared to the value of 6.55 (99)° in (I).

In the structure, the pairs of O—H···O and N—H···O intermolecular hydrogen bonds pack the molecules into zigzag chains (Table 1, Fig.2).

Experimental top

Maleic anhydride (0.025 mol) in toluene (25 ml) was treated dropwise with 4-chloro-3-nitroaniline (0.025 mol) also in toluene (20 ml) with constant stirring. The resulting mixture was stirred for about 30 min and set aside for an additional 30 min at room temperature for the completion of reaction. The mixture was then treated with dilute hydrochloric acid to remove the unreacted 4-chloro-3-nitroaniline. The resultant solid N-(4-Chloro-3-nitrophenyl)maleamic acid was filtered under suction and washed thoroughly with water to remove the unreacted maleic anhydride and maleic acid. It was recrystallized to constant melting point from ethanol. The purity of the compound was checked and characterized by its infrared spectra.

Rod like colorless single crystals of the title compound used in X-ray diffraction studies were grown in an ethanol solution by slow evaporation of the solvent (0.5 g in about 30 ml of ethanol) at room temperature.

Refinement top

The H atoms of the NH group and the OH group were located in a difference map and later restrained to the distance N—H = 0.86 (2) Å and O—H = 0.82 (2) Å, respectively. The other H atoms were positioned with idealized geometry using a riding model with the aromatic C—H = 0.93 Å and methylene C—H = 0.97 Å. All H atoms were refined with isotropic displacement parameters set at 1.2Ueq.

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.
