It was characterized by ele- mental analysis, IR and X-ray single crystal diffraction analysis. The crystal of the title complex [Cu(C9H9BrNO2)2] belongs tomonoclinic, space group P21/ n with a=1.319 1(5)nm, b=0.444 58(16)nm, c=1.656 7(6)nm, β=91.226(5)°, V=0.97146(6) nm3, Z=2, Dc=1.879 Mg·m-3, μ=5.264 mm-1, F(000)=542, and final R1=0.0456, wR2=0.0970. The complex comprises a four-coordinated copper! center, with an N2O2 planar coordination environment. The molecules are connected by hydrogen bonds to form two-dimensional layered structure.
