| 摘 要： | A lead(Ⅱ) coordination polymer, {Pb2(butca)(H2O)2](H2O)2}n (1), has been synthesized by the hydrothermal reaction of Pb(OH)2 and 1, 2, 3, 4-butanetetracarboxylic acid (H4butca) at 160 ℃. Single-crystal X-ray analyses reveal that it crystallizes in monoclinic, space group P21/c with a = 7.616(5), b = 7.584(4), c = 12.314(7) (A), β = 105.595(12)°, V = 685.0(7) (A)3, Z = 4,C8H14O12Pb2, Mr= 716.57, Dc=3.474 g/cm3,μ = 24.610 mm-1, F(000) = 644, the final R = 0.0381 and wR = 0.1176 for 1465 observed reflections with Ⅰ＞ 2σ(Ⅰ). The complex presents a 2D-layered structure featuring two different types of rings, and has a (4,3 6) topology based on Pb and butca 4- nodes. In solid state, complex 1 shows photoluminescence with the maximum emission intensity at 468 nm under 286 nm excitation.
