(2E)-N-(3,5-Dibromo-4-methoxyphenyl)-2-(hydroxyimino)acetamide
The title compound, C(9)H(8)Br(2)N(2)O(3), is planar (r.m.s. deviation = 0.030 Å) with the exception of the terminal methyl group which lies out of the plane [1.219 (3) Å]. The conformation about the C=N double bond [1.268 (3) Å] is E. An intra-molecular N-H⋯N hydrogen bond occurs. Linear supra-molecular chains along the b axis mediated by O-H⋯O hydrogen-bonding inter-actions feature in the cry...

In the title compound, C(17)H(17)NO(2), the phenyl-ene rings are nearly coplanar [dihedral angle 7.3 (1)°]. The acetamido group is twisted out of the plane of the aromatic ring in order to form an N-H⋯O hydrogen bond to the acetamido group of an adjacent mol-ecule, generating a helical chain running along the b axis.

The title compound, C(14)H(10)Br(2)N(2)O(3)·H(2)O, was synthesized by the reaction of 3,5-dibromo-2-hydroxy-benzaldehyde with an equimolar amount of 4-hydroxy-benzohydrazide in methanol. The structure comprises a Schiff base unit and a water mol-ecule of crystallization. The dihedral angle between the benzene rings in the Schiff base is 1.3 (3)°. In the crystal structure, mol-ecules are linked ...

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 asymmetric unit of the title compound, C(14)H(9)Br(2)ClN(2)O(2), contains two independent mol-ecules. Both mol-ecules adopt an E configuration about the C=N bond. The dihedral angles between the benzene rings are 30.0 (2) and 51.6 (2)° in the two mol-ecules. In the crystal, mol-ecules are linked through N-H⋯O hydrogen bonds, forming chains along the b axis. In addition, there is an intra-mo...
