Oxamidato-bridged heterotrinuelear complex [Zn（CuL）2N3]（Cl04）·1.25 H2O was been synthesized and characterized by IR,electronic spectra and fluorescence spectra. The crystal structure was determained. The complex crystallizes in the orthorhombic. Space group Pbcn, a=1. 424 2（7） nm,b=1. 227 6（5）nm, c=3. 464 8（15） nm, Z=8,RI=0. 097 1, ωR2= 0. 159 2. The electronic spectra has been fitted by Gaussian and correlative coorination parameters have been obtained. The fluorescence spactra of title complex and Zn （Cl04）2 were campared and discussed.
