摘      要:N′-(4-fluorobenzylidene)-2-( 1H-1,2,4-triasole-1-yl) acetohydrazide was synthesized by the reaction of 4-flu- orobenzaldehyde with 2-( 1H-1,2,4-triazole-1-yl) acetohydrazide. The structure was confirmed via elemental analysis, MS, ^1H NMR, IR, and X-ray diffraction. It crystallized in a monoclinic system with space group P2 ( 1 ), α = 0.4905(1) nm, b =0. 8160(2) nm, c = 1.4105(3) nm, β =93. 33(3)°, Z=2, V=0.5636(2) nm^3, Do =1.457 Mg/m^3,μ =0. 112 mm^-1 , F(000) =256, and final R1 =0. 0685. Several intermolecular hydrogen-bond interactions existed in the crystal structure, facilitating the stabilization of the compound.
