N-(4-Chloro-3-nitrophenyl)succinamic acid
In the title compound, C(10)H(9)ClN(2)O(5), the nitro group is significantly twisted out of the plane of the benzene ring to which it is attached [dihedral angle = 27.4 (6)°]. In the crystal, mol-ecules are linked into centrosymmetric dimers via pairs of O-H⋯O hydrogen bonds. These dimers are further linked by N-H⋯O hydrogen bonds into double chains running along the a axis.

In the title compound, C(11)H(10)ClNO(3), the dihedral angle between the benzene ring and the amide group is 6.6 (10)° and an intramolecular O-H⋯O hydrogen bond occurs. In the crystal, molecules are linked by N-H⋯O hydrogen bonds, generating C(7) zigzag chains.

The title compound, C(11)H(12)ClNO(3), crystallizes with two independent mol-ecules in the asymmetric unit in which the dihedral angles between the benzene ring and the amide group are 55.0 (2) and 28.2 (3)°. The two independent mol-ecules are linked by an N-H⋯O hydrogen bond. In the crystal, mol-ecules form inversion dimers via pairs of O-H⋯O hydrogen bonds. These dimers are linked into sheets...

In the mol-ecule of the title compound, C(10)H(7)ClN(2)O(5), 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 ato...

In the crystal structure of the title compound, C(11)H(12)ClNO(3), the asymmetric unit contains two independent mol-ecules. The N-H bond in the amide segment is anti to the meta-Cl atom in the benzene ring, in both molecules. The amide and carboxyl C=O bonds are also anti to each other and anti to the H atoms on the adjacent -CH(2) groups. Furthermore, the C=O and O-H bonds of the acid group ar...
