2,4-Dinitrobenzaldehyde hydrazone
The title compound, C(7)H(6)N(4)O(4), plays an important role in the synthesis of biologically active compounds. The planar hydrazone group is oriented at a dihedral angle of 8.27 (3)° with respect to the benzene ring. In the crystal structure, inter-molecular N-H⋯O and N-H⋯N hydrogen bonds link the mol-ecules.
متن کامل(E)-Benzaldehyde (2,4,6-trichlorophenyl)hydrazone
The title compound, C(13)H(9)Cl(3)N(2), was obtained from a condensation reaction of benzaldehyde and 2,4,6-trichloro-phenyl-hydrazine. The mol-ecule assumes an E configuration with the phenyl ring and trichloro-phenyl ring located on opposite sides of the C=N bond. The phenyl ring is oriented at a dihedral angle of 42.58 (12)° with respect to the tricholorophenyl ring. In the crystal, the mol-...
متن کاملBiological activities of hydrazone derivatives.
There has been considerable interest in the development of novel compounds with anticonvulsant, antidepressant, analgesic, antiinflammatory, antiplatelet, antimalarial, antimicrobial, antimycobacterial, antitumoral, vasodilator, antiviral and antischistosomiasis activities. Hydrazones possessing an azometine -NHN=CH- proton constitute an important class of compounds for new drug development. Th...
متن کاملHydrogen-bonded dimers in 2-nitrobenzaldehyde hydrazone and a three-dimensional hydrogen-bonded framework in 3-nitrobenzaldehyde hydrazone.
Molecules of 2-nitrobenzaldehyde hydrazone, C7H7N3O2, where Z' = 2, are linked by two N-H...N hydrogen bonds into isolated dimers, whereas in the isomeric 3-nitrobenzaldehyde hydrazone, where Z' = 1, the molecules are linked by one N-H...O hydrogen bond and one N-H...N hydrogen bond into a three-dimensional framework structure.
