N-(4-Chloro-3-nitro-phen-yl)succinamic acid.

ABSTRACT: 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.

N-(2-Chloro-phen-yl)succinamic acid.

Project description:The conformations of the N-H and C=O bonds in the amide segment of the structure of the title compound {systematic name: 3-[(2-chloro-phen-yl)amino-carbon-yl]propionic acid}, C(10)H(10)ClNO(3), are trans to each other, while the conformation of the amide H atom is syn to the ortho-chloro group in the benzene ring. Further, the conformations of the amide O atom and the carbonyl O atom of the ester segment are also trans to the H atoms attached to the adjacent C atoms. In the crystal structure, mol-ecules are packed into infinite chains through inter-molecular N-H?O and O-H?O hydrogen bonds.

N-(4-Chloro-3-methyl-phen-yl)succinamic acid.

Project description: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 parallel to (11-3) via N-H?O hydrogen bonds.

N-(2-Chloro-5-methyl-phen-yl)succinamic acid.

Project description:In the title compound, C(11)H(12)ClNO(3), the conformation of the N-H bond in the amide segment is syn with respect to the ortho-Cl atom. The amide and carboxyl C=O groups are syn to each other. Furthermore, the C=O and O-H bonds of the carboxyl group are in syn positions with respect to each other. The dihedral angle between the benzene ring and the amide group is 47.8?(2)°. In the crystal, mol-ecules are connected by pairs of O-H?O hydrogen bonds, forming inversion dimers. The dimers are further linked by N-H?O hydrogen bonds into double chains along the b-axis direction.

N-(4-Chloro-phen-yl)succinamic acid.

Project description:In the title compound, C(10)H(10)ClNO(3), the conformation of the amide O atom and the carbonyl O atom of the acid segment are anti to each other and further, they are anti to the H atoms of their adjacent -CH(2) groups.

N-(4-Chloro-3-nitro-phen-yl)maleamic acid.

Project description: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 atoms, which are almost coplanar (r.m.s. deviation for non-H atoms except the nitro group = 0.202 Å). In the crystal, N-H⋯O hydrogen bonds link the mol-ecules into zigzag chains running along the b axis.

N-(4-Methyl-2-nitro-phen-yl)succinamic acid.

Project description:In the title compound, C(11)H(12)N(2)O(5), the conformation of the N-H bond in the amide segment is syn to the ortho-nitro group in the benzene ring. The amide C=O and the carboxyl C=O of the acid segment are syn to each other and both are anti to the H atoms on the adjacent -CH(2) groups. Furthermore, the C=O and O-H bonds of the acid group are in syn positions with respect to each other. The dihedral angle between the benzene ring and the amide group is 36.1?(1)°. The amide H atom shows bifurcated intra-molecular hydrogen bonding with an O atom of the ortho-nitro group and an inter-molecular hydrogen bond with the carbonyl O atom of another mol-ecule. In the crystal, the N-H?O(C) hydrogen bonds generate a chain running along the [100] direction. Inversion dimers are formed via a pair of O-H?O(C) interactions, that form an eight-membered hydrogen-bonded ring involving the carboxyl group.
