The title complex Cu(L)2 [HL=N-(5-bromosalicylidene)-2-aminoethanol] was synthesized by the reaction of Cu(CH3COO)2·H2O with N-(5-bromosalicylidene)-2-aminoethanol in the ethanol. 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. CCDC: 274180.
The title complex Cu(L)2 (HL=o-vanillin hydrazone) was synthesized by the reaction of Cu(CH3COO)2·H2O with o-vanillin hydrazone in the ethanol.
