Its structure was characterized by IR, 1H NMR, Elemental Analyzer and X-ray single-crystal diffraction. Fluorescent property about the title compound complexed with five kinds of metal ions was inves- tigated. The results show that the compound crystallizes in the monoclinic space group P2(1)/n with cell parameters: a = 0.7603 nm, b = 0.7508 nm, c = 2.7246 nm, α= 90.00˚, β= 95.43˚, γ= 90.00˚. 3 3 −1 −3 V = 1.548 nm , Z = 4, Dc = 1.314 g/cm , μ= 0.088 mm , F (000) = 648, ρ = 218 e∙nm , ρ = −155 max min e∙nm−3. The complexes exhibited strong fluorescence absorption at 676 nm (λ ). Fluorescence max enhancement effect produced by Cu2+, Co2+ is remarkable.
