摘要
羧酸配位聚合物是金属离子与有机羧酸构造块通过配位键或其他分子间弱作用力经自组装而成的一维、二维、三维的聚合物。由于这些配位聚合物具有新颖的拓扑结构以及在功能材料方面的潜在应用。同时又由于羧酸配合物比较稳定,所以设计和调控特殊配位聚合物成了当前的研究热点。
A coordination polymer [Zn4(1,8-nap)4(4,4′-bipy)2-0.5en .H2O]n (where 1,8-nap is 1,8-naphthalenedicarboxylate, 4,4′ -bipy is 4,4′-bipyridine and en is ethylenediamine) has been hydrothermally synthesized and characterized by elemental analysis, IR, TG and single crystal X-ray diffraction. The title complex belongs to triclinic system with space group Pl, α=1.02694(2) nm, b=1.134 52(2) nm, c=1.348 64(3) nm, α=79.992^o, β= 73.838^o, γ=84.246^o, V=1.484 nm^3, Z=1, Mt=1478.59, Dc=1.655 g·cm^-3, R=0.031 8, wR =0.087 6. The crystal structure of title complex shows that four 1,8-naphthalenedicarboxylate ligands coordinate with zinc atoms to form tetranuclear units which are further connected via 4,4′-bipy ligands to generate 1D double-chain structure. The luminescent property of the complex is also studied in this oaoer. CCDC: 657266.
