(E)-N′-(3,5-Dibromo-2-hydroxybenzylidene)-2-nitrobenzohydrazide methanol solvate
In the title compound, C(14)H(9)Br(2)N(3)O(4)·CH(3)OH, the Schiff base mol-ecule adopts an E geometry with respect to the C=N bond and the benzene rings are oriented at a dihedral angle of 45.3 (2)°. An intra-molecular O-H⋯N hydrogen bond helps to establish the conformation. In the crystal, the methanol solvent mol-ecule is linked to the Schiff base mol-ecule through an O-H⋯O hydrogen bond and ...

The title Schiff base compound, C(14)H(9)Br(2)ClN(2)O(2)·CH(4)O, was derived from the condensation reaction of 3,5-dibromo-salicylaldehyde with 2-chloro-benzohydrazide. The dihedral angle between the two benzene rings is 48.2 (2)°. In the crystal structure, mol-ecules are linked through O-H⋯O and N-H⋯O inter-molecular hydrogen bonds, forming layers parallel to the bc plane. There is also an O-H...

In the title compound, C(14)H(9)I(2)N(3)O(4)·CH(3)OH, the Schiff base mol-ecule adopts an E geometry with respect to the C=N bond and the dihedral angle between the benzene rings is 45.0 (2)°; an intra-molecular O-H⋯N hydrogen bond is present. In the crystal, adjacent Schiff base mol-ecules are linked by methanol solvent mol-ecules through inter-molecular N-H⋯O and O-H⋯O hydrogen bonds, forming...
متن کامل(E)-N′-(4-Nitrobenzylidene)-2-(8-quinolyloxy)acetohydrazide methanol solvate
In the title compound, C(18)H(14)N(4)O(4)·CH(3)OH, the mean planes of the benzene ring and the quinoline ring system make a dihedral angle of 15.5 (2)°. The methanol solvent mol-ecule forms an O-H⋯N hydrogen bond to the quinoline ring system and accepts an N-H⋯O hydrogen bond from the hydrazide NH group. The mol-ecules lie in layers approximately parallel to (101) and C-H⋯O inter-actions exist ...
