Crystal structure of N'-[4-(di-methyl-amino)-benzyl-idene]furan-2-carbohydrazide monohydrate.

Project description:The condensation of 2-furoic hydrazide and 4-dimethyl amino-benzaldehyde in ethanol yielded a yellow solid formulated as the title compound, C14H15N3O2·H2O. The crystal packing is stabilized by inter-molecular O(water)-H?O,N(carbohydrazide) and N-H?O(water) hydrogen bonds, which form a two-dimensional network along the bc plane. Additional C-H?O inter-actions link the mol-ecules into a three-dimensional network. The dihedral angle between the mean planes of the benzene and the furan ring is 34.47?(6)°. The carbohydrazide moiety, i.e., the C=N-N-C=O fragment and the benzene ring are almost coplanar, with an angle of 6.75?(9)° between their mean planes.

Project description: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 bifurcated N-H?O(N) hydrogen bonds into chains along [001].

(E)-N'-(2-Hy-droxy-benzyl-idene)furan-2-carbohydrazide.

Project description: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.

N'-[(E)-2-Hy-droxy-5-iodo-benzyl-idene]furan-2-carbohydrazide monohydrate.

Project description: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-molecular O-H?N(imine) hydrogen bond is formed. In the crystal, the water mol-ecule accepts a hydrogen bond from an amine H atom, and forms two O-H?O(carbon-yl) hydrogen bonds, thereby linking three different carbohydrazide mol-ecules. The result is a supra-molecular layer parallel to (001). The closest contacts between layers are of the type I?I, at a distance of 3.6986?(6)?Å.
