Two mixed-ligand polymeric complexes formulated as {[Zn(pda)(bpy)]·0.5H2O}n (pda = 1,4-phenylenediacetate, bpy = 2,2·-bipyridine) 1 and {[Cd(pda)(bpy)]·1.5H2O}n 2 have been hydro- thermally synthesized. Single-crystal X-ray diffraction analyses reveal that the structures of com- plexes 1 and 2 possess similar one-dimensional zigzag chains. Crystal data for compound 1: monocli- nic, space group P21/c, a = 15.965(2), b = 8.305(1), c = 14.856(2) , β = 111.048(2)o, Mr = 422.73, V = 1838.2(4) 3, 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) + (0.0351P)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) , β = 99.59(3)o, Mr = 487.75, V = 3859.9(14) 3, Z = 8, Dc = 1.668 g/cm3, μ = 1.169 mm-1, F(000) = 1936, the final R = 0.0723 and wR = 0.1612 (w = 1/[σ2(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 1 and 475 nm for 2) upon excitation at 330 nm.
