N′-[(E)-4-Hydroxy-3-methoxybenzylidene]pyridine-4-carbohydrazide
In the title compound, C(14)H(13)N(3)O(3), the two six-membered rings are oriented at a dihedral angle of 15.17 (11)° and an intra-molecular O-H⋯O hydrogen bond occurs. In the crystal, mol-ecules inter-act by way of N-H⋯O, O-H⋯N and C-H⋯O hydrogen bonds, thereby generating S(5) chain and R(2) (1)(7) ring motifs.

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 mol-ecule of the title compound, C(12)H(11)N(3)O(2), is approximately planar with an r.m.s. deviation of 0.0814 Å from the plane through all the non-H atoms. The dihedral angle formed by the benzene and isoxazole rings is 6.88 (16)°. The mol-ecular conformation is stabilized by an intra-molecular C-H⋯N hydrogen bond, forming an S(6) ring, and the mol-ecule displays an E configuration with r...

In the title compound, C12H9BrN4O, the N'-methyl-idene-pyrazine-2-carbohydrazide and 4-bromobenzene groups are oriented at a dihedral angle of 10.57 (7)°. The hydrazide N-H group is involved in intra-molecular N-H⋯N inter-action, which generates an S(5) motif. A short C-H⋯O inter-action is formed between the methyl-idene H atom and the carbonyl O atom. It connects mol-ecules into chains extendi...

In the title compound, C(13)H(12)N(2)O(2)S, the dihedral angle between the aromatic rings is 15.20 (11)°. In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds generate R(2) (2)(8) loops.
