【摘要】 Two new Zn coordination polymers,namely,[Zn L(o-bdc)]n(1) and [Zn L(mbdc)]n·n H2O(2)(L = 4?-(3-pyridyl)-3,2?:6?,3??-terpyridine,H2(o-bdc) = benzene-1,2-dicarboxylic acid,H2(m-bdc) = benzene-1,3-dicarboxylic acid),were synthesized by hydrothermal methods. The crystal structures have been determined by single-crystal X-ray diffraction. Compound 1 crystallizes in monoclinic C2/c space group,with a = 28.016(2),b = 11.3815(11),c = 19.8071(17) ?,β = 133.961(2)°,V = 4546.2(7) ?3,Z = 8,Mr = 539.83,Dc = 1.577 Mg/m3,μ = 1.127 mm-1,F(000) = 2208,the final R = 0.0426 and w R = 0.0986 for 2875 observed reflections with I > 2σ(I) and displays a 1D coordination chain. While compound 2 crystallizes in monoclinic C2/c space group,with a = 15.6003(14),b = 11.9152(11),c = 26.633(3) ?,β = 94.320(2)°,V = 4936.5(8) ?3,Z = 4,Mr = 1115.67,Dc = 1.496 Mg/m3,μ = 1.043 mm-1,F(000) = 2272,the final R = 0.0499 and w R = 0.1342 for 2659 observed reflections with I > 2σ(I) and shows a classical 3D cds topological network with point symbol of {65.8}. Furthermore,thermal stability and luminescent properties of 1 and 2 have also been investigated.
