Source of material
The title compound was synthesized by the reaction of (2,4-dinitro-phenyl)hydrazine (1 mmol, 198.1 mg) with 1-(3-chloro-4-fluorophenyl)ethan-1-one (1 mmol, 172.6 mg) in ethanol (30 mL) under reflux conditions (338 K) for 3 h. The solvent was removed and the solid product recrystallized from THF. After three days red single crystals were obtained.
Experimental details
All H atoms were placed in idealized positions (C—H = 0.93-0.96 Å, N—H = 0.86 Å ) and refined as riding atoms. The Uiso values were constrained to be 1.5Ueq of the carrier atom for methyl H atoms and 1.2Ueq for the remaining H atoms.
Discussion
2,4-Dinitrophenylhydrazones are important Schiff bases because of their significant molecular nonlinearities, remarkable ability to crystallize in non-centrosymmetric space groups and their biological activities [2], [3], [4], [5], [6], [7], [8], [9], [10]. As part of our interest in coordination chemistry of 2,4-dinitrophenylhydrazones, we have synthesized the title compound.
In the crystal structure of the title compound, there are two crystallographic independent molecules in the asymmetric unit. All bond lengths and angles are in normal range. The two aromatic rings in each independent molecule are almost coplanar, with the dihedral angle of 4.99(2)° and 1.08(2)°, respectively. The C—N bond lengths in the independent molecules are 1.277(6) Å (C7—N4) and 1.299(6) Å (C21–N7), respectively, which are much shorter than the typical C=N bond length (1.34 Å– 1.38 Å). The C—N—N angles in each independent molecule of 116.4(5)° and 116.9(5)° are smaller than the ideal value of 120° expected for sp2-hybridized N atoms.
