N'-(3-Bromo-5-chloro-2-hy-droxy-benzyl-idene)-2H-1,3-benzodioxole-5-carbo-hydrazide.

ABSTRACT: The asymmetric unit of the title hydrazone compound, C(15)H(10)BrClN(2)O(4), contains two independent mol-ecules. The dihedral angles between the benzene rings are 38.7?(3)° in one mol-ecule and 24.3?(3)° in the other. Both mol-ecules exist in trans conformations with respect to the C=N double bonds of the central methyl-idene units. Intra-molecular O-H?N contacts are observed in both mol-ecules, forming S(6) rings. In the crystal, mol-ecules are linked through N-H?O hydrogen bonds into chains along the a axis.

Project description:In the title compound, C(18)H(18)BrClN(2)O(2)·C(2)H(6)O, the hy-droxy group forms an intra-molecular O-H?N hydrogen bond, which influences the conformation of the Shiff base mol-ecule, where the two aromatic rings form a dihedral angle of 21.67?(8)°.

Project description:The mol-ecule of the title compound, C(10)H(11)N(3)O(3), adopts an all-trans conformation and is approxomately planar, the largest deviation from the least-squares plane through all non-H atoms being 0.261 (1) Å. An intra-molecular O-H⋯N hydrogen bond occurs. In the crystal, the mol-ecules are packed into layers lying parallel to the ab plane by π-stacking inter-actions between the benzene ring of one molecule and the C-N bond of the oxime group of another molecule; the shortest inter-molecular C⋯C separation within the layer is 3.412 (1) Å. The layers are connected by O-H⋯O and N-H⋯O hydrogen bonds.
