چکیده
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.

In the mol-ecular structure of the title compound, C(11)H(10)ClNO(3), the conformation of the N-H bond in the amide segment is syn to the ortho-methyl group in the phenyl ring. The C=O and O-H bonds of the acid group are in the relatively rare anti position with respect to each other. This is an obvious consequence of the hydrogen bond donated to the amide carbonyl group. The central oxobutenoi...

In the title compound, C(11)H(11)NO(3), the conformation of the N-H bond is anti to the C=O bond in the amide segment, while it is syn to the ortho-methyl group in the phenyl ring. In the maleamic acid unit, the amide C=O bond is anti to the adjacent C-H bond, while the carboxyl C=O bond is syn to the adjacent C-H bond. The C=O and O-H bonds of the acid group are in the relatively rare anti pos...

The title compound, C(10)H(7)ClN(2)O(5)·H(2)O, crystallizes with a half-mol-ecule each of N-(2-chloro-4-nitro-phen-yl)maleamic acid (located on a mirror plane) and water (located on a twofold rotation axis) in the asymmetric unit. The main mol-ecule is planar by symmetry and its conformation is stabilized by an intra-molecular O-H⋯O hydrogen bond. In the crystal, N-H⋯O and O-H⋯O hydrogen bonds ...

In the title compound, C(11)H(11)NO(4), the asymmetric unit contains two unique mol-ecules, both of which are almost planar, with r.m.s. deviations of 0.047 and 0.059 Å. The dihedral angles between the benzene ring and the plane of maleamic acid unit are 3.43 (5) and 5.79 (3)° in the two mol-ecules. The mol-ecular structures are stabilized by a short intra-molecular O-H⋯O hydrogen bond within e...

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...
