N′-(Butan-2-ylidene)furan-2-carbohydrazide
The title Schiff base compound, C(9)H(12)N(2)O(2), was obtained from a condensation reaction of butan-2-one and furan-2-carbohydrazide. The furan ring and the hydrazide fragment are roughly planar, the largest deviation from the mean plane being 0.069 (2)Å, but the butanyl-idene group is twisted slightly with respect to this plane by a dihedral angle of 5.2 (3)°. In the crystal, inter-molecular...

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...

In the title mol-ecule, C(12)H(10)N(2)O(3), the aromatic and furan rings form a dihedral angle of 8.89 (1)° and an intra-molecular N-H⋯O hydrogen bond occurs. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into zigzag chains running along the c axis.
متن کاملN-(2-Nitrophenyl)furan-2-carboxamide
In the title furan-carboxamide derivative, C11H8N2O4, the benzene and furan rings are rotated from the mean plane of the central fragment by 2.68 (5) and 7.03 (4)°, respectively. The nitro group forms a dihedral angle of 10.15 (5)° with the adjacent benzene ring. In the crystal, mol-ecules are linked by weak C-H⋯O inter-actions, forming helical chains running along [010].
متن کامل(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.
