(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 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.
متن کاملN′-[(E)-Furan-2-ylmethylidene]-4-hydroxybenzohydrazide
The title compound, C12H10N2O3, exists in the E conformation. The five-membered ring and the phenyl rings form dihedral angles of 36.73 (10) and 12.22 (10)°, respectively, with the central C(=O)N2C unit. The crystal packing is dominated by strong N-H⋯O and O-H⋯N hydrogen bonds. Together with weaker C-H⋯O inter-actions, these establish a three-dimensional supra-molecular network.
متن کاملVibrational hyperpolarizability of SF&
Expressions are derived for the vibrational second hyperpolarizability 1'" of SF 6' in the static limit and for the nonlinear-optical processes of the dc Kerr effect, electric-field-induced second harmonic generation (ESHO), and third harmonic generation (THO). These expressions give 1'" in terms of vibrational transition dipole, polarizability, and first hyperpolarizability matrix elements (f-...

The organic mol-ecule of the title monohydrate, C(12)H(9)IN(2)O(3)·H(2)O, features a disordered furyl ring with the major component [site occupancy = 0.575 (18)] having the carbonyl O and furyl O atoms syn, and the other conformation having these atoms anti. The mol-ecule is slightly twisted with the dihedral angle between the benzene and furyl rings being 10.3 (6)° (major component). An intra-...
