(E)-N′-(4-Methoxybenzylidene)pyridine-3-carbohydrazide dihydrate
In the title compound, C14H13N3O2·2H2O, the hydrazone mol-ecule adopts an E conformation with respect to the C=N bond. The dihedral angle between the benzene and pyridine rings is 8.55 (10)°. The methyl-idene-hydrazide [-C(=O)-N-N=C-] fragment is essentially planar, with a maximum deviation of 0.0375 (13) Å. The mean planes of the benzene and pyridine rings make dihedral angles of 2.71 (14) and...

The organic molecule in the title dihydrate, C12H9FN4O·2H2O, exists in the E conformation with respect to the azo-methane C=N double bond. The mol-ecule is approximately planar, with a maximum deviation of 0.117 (1) Å for the carbonyl O atom from the mean plane of the mol-ecule. Both pyridine rings are essentially coplanar with the central C(=O)N2C unit [dihedral angles = 1.99 (7) and 5.71 (8)°...

In the title compound, C12H9BrN4O, the dihedral angle between the aromatic rings is 12.16 (12)°. An intra-molecular N-H⋯N hydrogen bond closes an S(5) ring. In the crystal, C-H⋯O hydrogen bonds link the mol-ecules into C(6) chains propagating in [010]. Very weak aromatic π-π stacking [centroid-centroid separations = 3.9189 (15) and 3.9357 (15) Å] is also observed.

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, C(13)H(9)I(2)N(3)O(2), the dihedral angle between the two aromatic rings is 10.5 (2)°. The mol-ecule displays a trans configuration with respect to the C=N bond. An intra-molecular O-H⋯N hydrogen bond occurs. The crystal packing is stabilized by N-H⋯O and C-H⋯O hydrogen bonds.
