Ethyl 4-anilino-3-nitrobenzoate.

ABSTRACT: In the title compound, C(15)H(14)N(2)O(4), the aromatic rings are oriented at a dihedral angle of 78.33 (3)°. An intra-molecular N-H⋯O hydrogen bond results in a non-planar six-membered ring with a flattened-boat conformation. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules. π-π contacts between the phenyl rings and both the phenyl and benzene rings, [centroid-centroid distances = 3.841 (3) and 3.961 (3) Å] may further stabilize the structure.

Ethyl (E)-3-anilino-2-cyano-3-mercaptoacrylate.

Project description:In the title compound, C(12)H(12)N(2)O(2)S, there are S-H?N and N-H?O hydrogen-bond inter-actions. The N-H?O hydrogen bond is bifurcated, with the hydrogen being simultaneously donated to two equivalent O atoms, forming one intra- and one inter-molecular N-H?O bond with an R(1) (2)(4) motif. The motif of the S-H?N hydrogen bond is R(2) (2)(12).

Ethyl (Z)-4-ferrocenyl-2-(4-hy-droxy-anilino)-4-oxobutenoate.

Project description:In the title compound, [Fe(C(5)H(5))(C(17)H(16)NO(4))], the O=C-C=C-N mean plane is twisted with respect to the mean planes of the benzene and substituted cyclo-penta-dienyl rings by 44.2?(2) and 13.8?(3)°, respectively.
