摘　　要：A new hydrazone Schiff base(N,N′-bis[1-(5-Br-2-methoxyphenol-6-yl)methylidene]benzil dihydrazone)(1)and its copper(II)complex Cu2(L)2·H2O·0.25CH3OH(2)have been synthesized and characterized by IR,elemental analysis,1H-NMR and single-crystal X-ray analysis.The crystal of the complex(2)belongs to triclinic,space group Pī with a=12.993(13),b=14.454(15),c=16.291(17),α=102.309(14)°,β=91.327(14)°,γ=95.526(15)°,V=2972(5)3,Dc=1.642 g/cm3,Z=2,Mr =1469.77,μ(Mo Kα)=3.467mm-1,F(000)=1464.The complex(2)forms a 1D chain-like structure constructed by noncovalent interaction of Cu…N and Cu…Br and π-π stacking interactions.The adjacent chains are further interconnected into a 3D supramolecular architecture by the interaction of Br…Br.The fluorescence of the title compounds(1)and(2)were also discussed.A new hydrazone Schiff base（N,N′-bis[1-（5-Br-2-methoxyphenol-6-yl）methylidene]benzil dihydrazone）（1）and its copper（II）complex Cu2（L）2·H2O·0.25CH3OH（2）have been synthesized and characterized by IR,elemental analysis,1H-NMR and single-crystal X-ray analysis.The crystal of the complex（2）belongs to triclinic,space group Pī with a=12.993（13）,b=14.454（15）,c=16.291（17）,α=102.309（14）°,β=91.327（14）°,γ=95.526（15）°,V=2972（5）3,Dc=1.642 g/cm3,Z=2,Mr =1469.77,μ（Mo Kα）=3.467mm-1,F（000）=1464.The complex（2）forms a 1D chain-like structure constructed by noncovalent interaction of Cu…N and Cu…Br and π-π stacking interactions.The adjacent chains are further interconnected into a 3D supramolecular architecture by the interaction of Br…Br.The fluorescence of the title compounds（1）and（2）were also discussed.
