N-(2,5-Dichlorophenyl)maleamic acid

چکیده
The asymmetric unit of the title compound, C(10)H(7)Cl(2)NO(3), contains two independent mol-ecules. The mol-ecular conformation of each maleamic unit is stabilized by an intra-molecular O-H⋯O(carbon-yl) hydrogen bond owing to the anti disposition of the participating entities. The mean planes through the benzene ring and the amido group are inclined at angles of 45.7 (1) and 40.8 (1)° in the two mol-ecules. In the crystal, the independent mol-ecules self-associate via N-H⋯O hydrogen bonds into zigzag ribbons propagating along the a axis. The ribbons are weakly coupled by C-H⋯π and C-H⋯O inter-actions.

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...

The asymmetric unit of the title compound, C(10)H(7)Cl(2)NO(3), contains two unique mol-ecules, both being stabilized by an intra-molecular O-H⋯O hydrogen bond within their maleamic units. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into chains extending along [1] which are further assembled into sheets via short inter-molecular C-Cl⋯O=C contacts [3.102 (2...
متن کاملDeciphering the genetic determinants for aerobic nicotinic acid degradation: the nic cluster from Pseudomonas putida KT2440.
The aerobic catabolism of nicotinic acid (NA) is considered a model system for degradation of N-heterocyclic aromatic compounds, some of which are major environmental pollutants; however, the complete set of genes as well as the structural-functional relationships of most of the enzymes involved in this process are still unknown. We have characterized a gene cluster (nic genes) from Pseudomonas...
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...
