(E)-N′-(2-Hydroxybenzylidene)furan-2-carbohydrazide
In the title compound, C(12)H(10)N(2)O(3), the dihedral angle between the benzene ring and the furan ring is 16.12 (13)°. The conformation is stabilized by an intra-molecular O-H⋯N hydrogen bond. Inter-molecular N-H⋯O hydrogen bonds with the keto group as acceptor lead to strands along [001]. The mol-ecule displays a trans configuration with respect to the C=N and N-N bonds.

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-Fluorobenzylidene)furan-2-carbohydrazide
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-Chlorobenzylidene]thiophene-2-carbohydrazide
There are two independent mol-ecules in the asymmetric unit of the title compound, C12H9ClN2OS, a Schiff base derived from hydrazide, in which the dihedral angles between the thio-phene and benzene rings are 3.6 (3) and 7.3 (3)°. In the crystal, the two independent mol-ecules are arranged about an approximate non-crystallographic inversion center and are connected by two N-H⋯O hydrogen bonds. W...
متن کاملN′-[(E)-2,6-Dichlorobenzylidene]pyrazine-2-carbohydrazide
The title compound, C(12)H(8)Cl(2)N(4)O, is non-planar, the dihedral angle formed between the pendant pyrazine and benzene rings being 12.55 (11)°. An intra-molecular N-H⋯N hydrogen bond occurs. The amide groups self-associate via N-H⋯O hydrogen bonding, forming supra-molecular chains with base vector [101], which are stabilized by C-H⋯O contacts. C-H⋯N inter-actions are formed orthogonal to th...
