Crystal structure of 4-meth­oxy-N-phenyl­benzamide

In the title mol­ecule, C₁₄H₁₃NO₂, the dihedral angle between the planes of the benzene rings is 65.18 (4)°. The central amide group has about the same degree of twist with respect to both ring planes, as indicated by the dihedral angles of 34.70 (8) and 30.62 (8)° between its plane and that of the phenyl and 4-meth­oxy­benzene rings, respectively. The C atom of the meth­oxy group is close to being coplanar with its attached ring [deviation = −0.112 (2) Å]. In the crystal, mol­ecules are linked by inter-amide N—H...O hydrogen bonds, which generate C(4) chains propagating in the [100] direction. Adajcent mol­ecules in the chain are related by translational symmetry.

Crystal structure of (Z)-2-hy­droxy-N′-(4-oxo-1,3-thia­zolidin-2-yl­idene)benzohydrazide

In the title compound, C₁₀H₉N₃O₃S, the five-membered ring adopts a slightly twisted conformation about the C_m—S (m = methyl­ene) bond. The dihedral angle between this ring and the benzene ring is 7.99 (9)°. A bifurcated intra­molecular N—H...(O,S) hydrogen bond helps to establish the near planar conformation of the mol­ecule. In the crystal, mol­ecules are linked by N—H...O and O—H...O hydrogen bonds to generate (001) sheets.
