Crystal structure of N'-(2,6-dichlorobenzylidene)-4- nitrobenzohydrazide, C14H9Cl2N3O3

C 14 H 9 Cl 2 N 3 O 3 ,monoclinic, P121/c1(no.14), a =10.960(2)Å, b =14.223(2)Å, c =9.149(1) Å, b =92.92(1)°,V =1424.3Å 3 , Z =4,R gt (F) =0.045, wR ref (F 2 ) =0.116, T =293 K.Source of material 2,6-Dichlorobenzaldehyde (2 mmol, 0.35 g) was dissolved in anhydrous methanol (10 ml), the mixture was stirred for several minutes at room temperature, 4-nitrobenzohydrazide (2 mmol 0.362 g) in methanol (5 ml) was added dropwise and stirred at room temperature for 2h,then for4hatRTand evaporated to dryness.The product was separated and recrystallised in methanol, redsinglecrystalswereobtainedafter 3d.
