N′-(3-Thienylmethylene)pyridine-2-carbohydrazide
The title compound, C(11)H(9)N(3)OS, was prepared to investigate the coordination chemistry of thio-phene-containing ligands as precursors to inter-esting metallopolymers. The mol-ecule is nearly planar. The angle between the thio-phene and pyridine rings is 8.63 (4)° and features the expected trans configuration about the imine bond. The structure is stabilized by a weak inter-molecular N-H⋯O ...
متن کاملN′-[(E)-3-Bromobenzylidene]pyrazine-2-carbohydrazide
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.

In the mol-ecule of the title compound, C(20)H(18)N(2)O(4), the dihedral angle between the benzene ring and the naphthyl ring system is 8.5 (2)°. In the crystal structure, mol-ecules are linked through inter-molecular O-H⋯O hydrogen bonds, forming chains running along the b axis.
متن کامل(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].
متن کاملN′-Benzylidenefuran-2-carbohydrazide
In the title compound, C(12)H(10)N(2)O(2), the dihedral angle between the benzene ring and the furan ring is 24.6 (2)°. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds, generating C(4) chains propagating in [010].
