چکیده
The title compound, C(10)H(6)Cl(3)NO(3), crystallizes with two independent mol-ecules in the asymmetric unit. The mol-ecular structure is stabilized by a short intra-molecular O-H⋯O hydrogen bond within the maleamic unit. In the crystal, each mol-ecule self-associates via N-H⋯O hydrogen bonds into chains, each running along the b axis. Two short inter-molecular Cl⋯O contacts [3.1267 (15) and 3.0523 (12) Å] and C-H⋯O inter-actions inter-connect these chains into a three-dimensional network.

In the crystal structure of the title compound, C(10)H(6)Cl(3)NO(3), the conformation of the amide bond is trans. The C=O and O-H bonds of the acid group are in the relatively rare anti position to each other. This is a consequence of the intra-molecular O-H⋯O hydrogen bond donated to the amide carbonyl group stabilizing the mol-ecular structure. In the crystal, inter-molecular N-H⋯O hydrogen b...

In the title compound, C(11)H(7)Cl(3)N(3)O, the dihedral angle between the benzene and cyclo-propane rings is 85.8 (2)°. In the crystal, mol-ecules are linked by C-H⋯O inter-actions, generating C(5) chains propagating in the a-axis direction.
متن کاملUnusual crystal structure of N-substituted maleamic acid - very strong effect of intramolecular hydrogen bonds.
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-r...

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(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...
