(E)-2-[(E)-3-(Hydroxyimino)butan-2-ylidene]-N-methylhydrazinecarbothioamide
In the title compound, C(6)H(12)N(4)OS, an intra-molecular N-H⋯N hydrogen-bond is present giving rise to an S(5) ring motif. In the crystal, double-stranded chains propagating along [10[Formula: see text]] are formed via pairs of O-H⋯S and N-H⋯S hydrogen bonds. The chains are further stabilized by C-H⋯S interactions.

The asymmetric unit of the title Schiff base compound, C(12)H(15)N(3)O, contains two crystallographically independent mol-ecules, with both existing in an E configuration with respect to the C=N double bonds. In the crystal structure, inter-molecular N-H⋯N and C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network.

The title compound, C(12)H(9)FN(2)O(2), was prepared by the reaction of 2-fluoro-benzaldehyde and furan-2-carbohydrazide. The furan ring is disordered over two sets of sites with refined occupancies of 0.60 (3):0.40 (3). The major and minor components of the furan ring make dihedral angles of 51.9 (6) and 38.0 (10)°, respectively, with the benzene ring. In the crystal, mol-ecules are linked via...
متن کاملN′-[(E)-2-Methoxybenzylidene]pyrazine-2-carbohydrazide
In the title compound, C(13)H(12)N(4)O(2), all the non-H atoms lie on a crystallographic mirror plane and an intra-molecular N-H⋯N hydrogen bond generates an S(5) ring; the conformation about the imine bond [1.280 (3) Å] is E. In the crystal, mol-ecules assemble into a two-dimensional array via C-H⋯O(carbon-yl) and C-H⋯N(pyrazine) contacts. Layers stack along the b-axis direction via weak π-π i...
متن کامل(E)-N′-(2-Chlorobenzylidene)-2-methoxybenzohydrazide
The mol-ecule of the title compound, C(15)H(13)ClN(2)O(2), displays an E configuration about the C=N bond. The dihedral angle between the two benzene rings is 77.1 (2)°. In the crystal structure, mol-ecules are linked through inter-molecular N-H⋯O hydrogen bonds, forming chains running along the b axis.
