Two mixed-ligand polymeric complexes formulated as {[Zn(pda)(bpy)]·0.5H2O}n (pdathermally synthesized. Single-crystal X-ray diffraction analyses reveal that the structures of complexes 1 and 2 possess similar one-dimensional zigzag chains. Crystal data for compound 1: monoclinic, space group P21/c, a = 15.965(2), b = 8.305(1), c = 14.856(2) (A),β= 1 1 1.048(2)°, Mr = 422.73, V= 1838.2(4) A3, Z= 4, Dc = 1.528 g/cm3, μ = 1.368 mm-1, F(000) = 868, the final R = 0.0783 and wR= 0.1469 (w=1/[σ2(Fo2) + (0.035 1p)2+ 8.0014P], where P = (Fo2+ 2Fc2)/3) based on 2025 observed reflections with I ＞ 2σ(I); and those for compound 2: monoclinic, space group C2/c, a = 29.921 (7), b= 8.5400(17), c = 15.320(3) (A),β= 99.59(3)°, Mr = 487.75, V = 3859.9(14) A3, Z = 8, Dc = 1.668g/cm3, μ = 1.169 mm-1, F(000) = 1936, the final R = 0.0723 and wR = 0.1612 (w = 1/[σ32(Fo2 ) +(0.0681p)2+ 55.9577P], where P = (Fo2+ 2Fc2)/3) based on 2130 observed reflections with I ＞ 2σ(I).Fluorescent analyses show that both complexes exhibit intense blue luminescence (λmax = 485 nm for 1and 475 nm for 2) upon excitation at 330 nm.
