Abstract：A novel mononuclear Schiff base complex, Ni(L){1, H3L=(3,5-dicloro-2-hydroxy-benzylidene)［N′-(3,5-dicloro-2-hydroxy-benzylidene)］-1-amino-N-aminoformimidic acid}, was synthesized through solvothermal in-situ synthesis method, using 3,5-dichloro-salicylaldehyde and carbohydrazide as raw materials, DMF and acetonitrile as solvent, nickel nitrate as ion source. The structure was characterized by FTIR, elemental analysis and single-crystal diffraction. 1(CCDC: 1 044 165) belongs to monoclinic system and space group P21/m. The cell parameters of 1 were a=10.416 6(5) ， b=6.516 2(3) ， c=13.479 1(6) ， β=109.330(5)°， V=863.34(7) 3， Z=2， Dc=1.834 g·cm-3， μ=1.764 mm-1， F(000)=474. Nickel(III) was coordinated with two nitrogen atoms and two oxygen atoms from L3-to form a rectangle-plane. The fluorescence property of 1 was investigated by FL. The result showed that 1 exhibited strong fluorescent property around 500 nm upon an excitation band at 435 nm in DMF.
