N′-(5-Chloro-2-hydroxy­benzyl­idene)-4-hydroxy­benzohydrazide

The title Schiff base compound, C(14)H(11)ClN(2)O(3), was prepared by the reaction of 5-chloro-salicylaldehyde and 4-hydroxy-benzohydrazide. The mol-ecule exists in a trans configuration with respect to the methyl-idene group. The dihedral angle between the two benzene rings is 40.1 (2)°. An intra-molecular O-H⋯N hydrogen bond helps to stabilize the mol-ecular conformation. In the crystal struc...

Methyl 5-chloro-2-(4-methyl­benzene­sulfonamido)­benzoate

In the title compound, C(15)H(14)ClNO(4)S, the benzene rings are oriented at a dihedral angle of 85.42 (1)°. An intra-molecular N-H⋯O hydrogen bond results in the formation of a five-membered ring and an intramolecular C-H⋯O inter-action also occurs.

N′-(5-Chloro-2-hy­droxy­benzyl­idene)-4-meth­oxy­benzohydrazide

The asymmetric unit of the title compound, C(15)H(13)ClN(2)O(3), contains two independent hydrazone mol-ecules. Each mol-ecule adopts an E configuration with respect to the methyl-idene unit and forms an intra-molecular O-H⋯N hydrogen bond. The principal difference between the two unique mol-ecules is the relative orientation of the two benzene rings, the dihedral angles between them being 4.0 ...
