A copper(Ⅱ) complex [CuL(H2O)(Sal)]·0.5H2O was obtained by the reaction of copper(Ⅱ) salicylate with 3-methyl-4-(4-methylphenyl)-5-(2-pyridyl)-1,2,4-triazole(L) in ethanol-water solution at room temperature.The crystal belongs to triclinic system with space group P1,and a=0.913 6(4) nm,b=1.122 2(5) nm,c=1.263 3(7) nm,α= 67.10(2)°,β=76.31(3)°,γ=68.17(2)°,V= 1.101(1) nm3,Z=2.The final refinement gave R1=0.039 8 and wR2=0.106 0 for 3 453 reflections with I>2σ(I).This complex is a good purple fluorescent material in solid state at room temperature.
