(2Z)-4-[(2-Hy-droxy-phen-yl)carbamo-yl]prop-2-enoic acid.

ABSTRACT: In the title compound, C(10)H(9)NO(4), the 2-hy-droxy-anilinic and the 4-oxobut-2-enoic acid groups are almost planar, with r.m.s. deviations of 0.0086 and 0.0262?Å, respectively. The dihedral angle between the two groups is 6.65?(1)°. Intra-molecular N-H?O, C-H?O and O-H?O hydrogen bonds form S(5), S(6) and S(7) ring motifs. In the crystal, the mol-ecules are dimerized due to C-H?O and O-H?O inter-molecular hydrogen bonds, with R(2) (2)(8) ring motifs. The dimers are inter-linked into polymeric chains along [010] with R(4) (3)(13) ring motifs by C-H?O, N-H?O and O-H?O hydrogen bonds.

Methyl (2Z)-3-[(4-nitro-phen-yl)carbamo-yl]prop-2-enoate.

Project description:In the title compound, C(11)H(10)N(2)O(5), the amide group is nearly coplanar and the ester group approximately perpendicular to the vinyl C-HC=CH-C group [dihedral angles of 5.0?(2) and 88.89?(5)°, respectively]. This results in a short intra-molecular O =C?O=C contact of 2.7201?(17)?Å between the amide O atom and the ester carbonyl C atom. The prop-2-enamide fragment and the nitro group make dihedral angles of 20.42?(6) and 13.54?(17)°, respectively, with the benzene ring. An intra-molecular C-H?O inter-action between the benzene ring and the amide group generates an S(6) ring motif. Inter-molecular C-H?O and N-H?O hydrogen bonds complete R(2) (2)(11) ring motifs and join mol-ecules into [100] chains.

Project description:In the title mol-ecule, C15H11Cl2NOS, the dihedral angle between the phenyl and benzene rings is 72.24 (1)°.

Project description:In the title compound, C(19)H(22)N(2)O(4), the dihedral angle between the aromatic rings is 67.33 (2)°. In the crystal, mol-ecules are linked through N-H⋯O and O-H⋯O hydrogen bonds, generating a two-dimensional network lying parallel to (100). As a result of the twist of the mol-ecular skeleton and the hindrance of the tert-butyl groups, no π-π inter-actions exist between the aromatic rings.
