N′-(3-Bromo-5-chloro-2-hydroxybenzylidene)-2H-1,3-benzodioxole-5-carbohydrazide
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-ecule...

Single crystals of the title compound, C(16)H(14)N(2)O(5)·H(2)O, were obtained from a condensation reaction of 1,3-benzodioxole-5-carbohydrazide and 3-methoxy-salicylaldehyde in a 95% ethanol solution. The asymmetric unit consists of a Schiff base mol-ecule, which assumes an E configuration with respect to the C=N bond, and a water mol-ecule of crystallization. The dihedral angle between the tw...

In the title compound, C12H8BrClN2O3, the furan ring makes a dihedral angle of 17.2 (2)° with the six-membered ring. An intra-molecular O-H⋯N hydrogen bond stabilizes the mol-ecular conformation. In the crystal, N-H⋯O hydrogen bonds connect the mol-ecules into chains running along the c-axis direction. The crystal packing is additionally stabilized by C-H⋯O inter-actions into a three-dimensiona...
متن کامل5-Chloro-N′-cyclohexylidene-3-methyl-1H-indole-2-carbohydrazide
In the title compound, C16H18ClN3O, the cyclo-hexane ring adopts a distorted chair conformation. In the crystal, pairs of mol-ecules are linked by N-H⋯O hydrogen bonds into inversion dimers, forming R 2 (2)(10) ring motifs. These dimers are connected through C-H⋯N hydrogen bonds into chains along the a axis, forming layers parallel to (101).

In the approximately planar title mol-ecule, C(14)H(10)BrClN(3)O(2), the dihedral angle between the aromatic ring planes is 5.79 (12)°. The conformation is stabilized by intra-molecular O-H⋯N and N-H⋯O hydrogen bonds and an inter-molecular O-H⋯O link leads to chains in the crystal propagating in [001].
