N-(2,6-Dimethyl-phen-yl)maleamic acid.

ABSTRACT: The asymmetric unit of the title compound, C(12)H(13)NO(3), contains two independent mol-ecules. The conformation of the N-H bond and the C=O bond in the amide segment are anti to each other. The mol-ecular conformation of each mol-ecule is stabilized by an intra-molecular O-H?O hydrogen bond. In the crystal, mol-ecules are connected through intermolecular N-H?O hydrogen bonds. In addition, there is a carbon-yl-carbonyl dipolar inter-action with an O?C contact of 2.926?(3)?Å.

N-(3,4-Dimethyl-phen-yl)maleamic acid.

Project description:The title compound, C(12)H(13)NO(3), crystallizes with four independent mol-ecules in the asymmetric unit. The N-H bond and the C=O bond in the amide segment are anti to each other. The C=C double bond is cis configured and an intra-molecular O-H?O hydrogen bond is formed in each molecule. The mean planes through the aromatic ring and the amide group -NHCO- are inclined at angles of 17.4?(3), 20.8?(2), 16.2?(2) and 11.2?(3)° in the four mol-ecules. In the crystal, inter-molecular N-H?O hydrogen bonds link the mol-ecules into ribbons along the b axis.

N-(2,4,6-Trimethyl-phen-yl)maleamic acid.

Project description:The mol-ecular structure of the title compound, C(13)H(15)NO(3), is stabilized by a short intra-molecular O-H?O hydrogen bond within the maleamic unit. In the crystal, inter-molecular N-H?O hydrogen bonds link mol-ecules into zigzag chains propagating in [010].

N-(3,5-Dichloro-phen-yl)maleamic acid.

Project description: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 contacts [Cl?O = 3.0897?(12) and 3.0797?(13)?Å].

N-(2,5-Dichloro-phen-yl)maleamic acid.

Project description: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?? and C-H?O inter-actions.

N-(3-Nitro-phen-yl)maleamic acid.

Project description:In the title compound, C(10)H(8)N(2)O(5), the mol-ecule is slightly distorted from planarity. The mol-ecular structure is stabilized by two intra-molecular hydrogen bonds. The first is a short O-H?O hydrogen bond (H?O distance = 1.57?Å) within the maleamic acid unit and the second is a C-H?O hydrogen bond (H?O distance = 2.24?Å) which connects the amide group with the benzene ring. The nitro group is twisted by 6.2?(2)° out of the plane of the benzene ring. The crystal structure manifests a variety of hydrogen bonding. The packing is dominated by a strong inter-molecular N-H?O inter-action which links the mol-ecules into chains running along the b axis. The chains within a plane are further assembled by three additional types of inter-molecular C-H?O hydrogen bonds to form a sheet parallel to the (01) plane.

N-(2,4,5-Trichloro-phen-yl)maleamic acid.

Project description: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.

N-(2-Methyl-phen-yl)maleamic acid.

Project description: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 position to each other. This is an obvious consequence of the intra-molecular O-H⋯O hydrogen bond donated to the amide carbonyl group. The ortho-substituted phenyl ring makes a dihedral angle of 12.7 (1)° with the mean plane of the maleamic acid unit. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into zigzag chains parallel to [001]. These chains are further linked into sheet by weak π-π inter-actions [centroid-centroid distance = 3.425 (2) Å].

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

Project description: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 15.2 (1)° with the phenyl ring. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into C(7) chains running [010].

Project description:The mol-ecule of the title compound, C(12)H(13)NO(2), lies on a twofold rotation axis that passes through the N and C(para) atoms as well as through the mid-point of the bond between the methyl-ene C atoms. The dihedral angle between the aromatic ring and the amide segment is 75.9?(1)°.
