Unusual crystal structure of N-substituted maleamic acid - very strong effect of intramolecular hydrogen bonds.

چکیده
N-Carbamylmaleamic acid (malur) undergoes cyclodehydration under favourable conditions, as expected, to give N-carbamyl maleimide. N-(Carboxymethyl) maleamic acid (malgly), however, does not undergo a similar cyclization reaction. Strong π bonding between the C and N of the amide group as well as two intramolecular hydrogen bonds makes malgly a planar molecule, as revealed by single-crystal X-ray studies.

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...

In the title compound, C(10)H(8)ClNO(3), the molecular conformation is stabilized by two intra-molecular hydrogen bonds. The first is a short O-H⋯O hydrogen bond within the maleamic acid unit and the second is a C-H⋯O hydrogen bond which connects the amide group with the phenyl ring. The maleamic acid unit is essentially planar, with an r.m.s. deviation of 0.044 Å, and makes a dihedral angle of...

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 title compound, C(10)H(7)Cl(2)NO(3), the asymmetric unit contains four independent mol-ecules, which are linked to each other by N-H⋯O hydrogen bonds. The mol-ecular structure is stabilized by a short intra-molecular O-H⋯O hydrogen bond within each maleamic acid unit. In the crystal, the mol-ecules are linked into networks through N-H⋯O hydrogen bonds and inter-molecular C-Cl⋯O=C contact...
