(E)-3-Chloro-N′-(2-fluorobenzylidene)thiophene-2-carbohydrazide
The title compound, C12H8ClFN2OS, is a hydrazide derivative adopting an E conformation with an azomethine N=C double bond length of 1.272 (2) Å. The mol-ecular skeleton is approximately planar; the terminal five- and six-membered rings form a dihedral angle of 5.47 (9)°. In the crystal, mol-ecules are linked by N-H⋯O and C-H⋯O hydrogen bonds into zigzag chains propagating in [100].

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 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...
