N′-(3,5-Dibromo-2-hydroxybenzylidene)-4-nitrobenzohydrazide methanol monosolvate
The title compound, C(14)H(9)Br(2)N(3)O(4)·CH(4)O, was obtained as the product of the reaction of 3,5-dibromo-salicyl-aldehyde with 4-nitro-benzohydrazide in methanol. The benzohydrazide mol-ecule is nearly planar, with a maximum deviation of 0.126 (2) Å. The mean planes of the two benzene rings make a dihedral angle of 9.3 (3)°. Intra-molecular O-H⋯N and O-H⋯Br inter-actions are observed in th...

The title Schiff base compound, C(14)H(9)Br(2)ClN(2)O(2)·CH(3)OH, features an intra-molecular O-H⋯N hydrogen bond, which contributes to the planarity of the mol-ecule: the dihedral angle between the two benzene rings is 4.6 (2)°. In the crystal, pairs of adjacent mol-ecules are linked through inter-molecular N-H⋯O and O-H⋯O hydrogen bonds, forming dimers. The methanol solvent mol-ecule is linke...

The title compound, C(15)H(13)ClN(2)O(3)·CH(3)OH, was synthesized by the condensation reaction of 2-hy-droxy-4-meth-oxy-benzaldehyde with 4-chloro-benzohydrazide in methanol. The Schiff base mol-ecule displays a trans configuration with respect to the C=N and C-N bonds. The dihedral angle between the two benzene rings is 5.3 (2)°. In the crystal, mol-ecules are linked by N-H⋯O and O-H⋯O hydroge...

The title compound, C(20)H(26)N(4)O(2)·CH(3)OH, was prepared by the reaction of 4-diethyl-amino-2-hy-droxy-benzaldehyde with 4-(dimethyl-amino)-benzohydrazide. The dihedral angle between the two benzene rings is 13.6 (3)° and an intra-molecular O-H⋯N hydrogen bond generates an S(6) ring. In the crystal, the hydrazone and methanol mol-ecules are linked through inter-molecular O-H⋯O and N-H⋯O hyd...

The asymmetric unit of the title compound, C(17)H(19)N(3)O(3)·CH(4)O, comprises two Schiff base mol-ecules and two methanol solvent mol-ecules. The Schiff base mol-ecules are approximately planar, with r.m.s. deviations from the planes defined by the non-H atoms of 0.107 and 0.154 Å, and with dihedral angles between the benzene rings of 4.49 (15) and 8.39 (15)°, respectively. This near-planarit...
