| 摘 要： | A lead(II) coordination polymer,{[Pb2(butca)(H2O)2](H2O)2}n (1),has been synthe-sized by the hydrothermal reaction of Pb(OH)2 and 1,2,3,4-butanetetracarboxylic acid (H4butca) at 160 °C.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),β=105.595(12)o,V=685.0(7)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 (4,36)topology based on Pb and butca4-nodes.In solid state,complex 1 shows photoluminescence with the maximum emission intensity at 468 nm under 286 nm excitation.
