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

ABSTRACT: 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.

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-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-(2-Methyl-phen-yl)succinamic acid.

Project description:In the crystal structure of the title compound, C(11)H(13)NO(3), the conformations of the N-H and C=O bonds in the amide segment are anti to each other and that of the amide H atom is syn to the ortho-methyl group in the benzene ring. In the crystal, O-H?O interactions lead to carboxylic acid inversion dimers and inter-molecular N-H?O hydrogen bonds link the mol-ecules into infinite chains. In addition, the crystal structure exhibits inter-molecular C-H?? inter-actions between one of the methyl H atoms and the benzene ring of neighbouring mol-ecules.

Project description:In the title compound, C(11)H(12)ClNO(3), the N-C=O fragment is twisted from the plane of the attached benzene ring by 48.39?(12)°. The carb-oxy-lic acid group is involved in O-H?O hydrogen bonding, which links pairs of mol-ecules into centrosymmetric dimers. N-H?O hydrogen bonds link these dimers, related by translation along the a axis, into ribbons.
