摘      要：A new nickel（II） complex [NiL2]（DMF）4 （HL = 2＇-[4-N,N＇-（dimethylamino- benzylidene）]-3,5-dihydroxybenzoylhydrazide） has been synthesized and its structure was characterized by IR,UV-Vis,1H NMR and elemental analysis. The fluorescence emission mechanism of the complex was discussed by fluorimetric spectra. The single-crystal structure was determined by X-ray diffraction analysis. The crystal belongs to the triclinic system,space group P1 with a = 0.9918（4）,b = 1.1297（4）,c = 1.1331（4） nm,α = 76.860（7）,β = 75.105（6）,γ = 89.022（7）°,V = 1.1936（8） nm^3,Z = 1,μ = 0.472 mm^-1,Dc = 1.319 g/cm^3,F（000） = 502 and Rint = 0.0913. In the title compound,the nickel（II） atom is four-coordinated with two nitrogen atoms from amide and two oxygen atoms from keto group. The complex is centrosymmetric with nickel located at the center.
