摘要： 以4,4′-联吡啶(bipy)、2,5-二巯基-1,3,4-三噻唑(H2SSS)为桥联配体,水热法合成了一新颖的三维结构配位聚合物[Zn2(SSS)2(bipy)]n(1),并用元素分析、IR和差热分析对配合物进行了表征,X-射线单晶衍射确定了配合物的结构。在该配合物中,每个配阴离子SSS2-桥联3个Zn2+,同时每个Zn2+连接3个配体构成一个与ab平面平行的二维网状结构,相邻网状结构再通过4,4′-bipy连接构成三维微空结构。

Abstract: A three-dimensional Zn2+ coordination polymer[Zn2(SSS)2(bipy)]n was prepared under hydrothermal method with 4,4'-bipyridine (bipy) and tridentate 1,3,4-thiadiazole-2,5-disulfide (SSS2-) as ligands and characterized by elemental analysis,IR spectrum and TG.Its structure was determined by single-crystal X-ray diffraction.In the title complex,each SSS2- anion links three Zn2+ ions while each Zn2+ links three SSS2- anions,constructing a two-dimensional plane which is parallel to the ab plane.Neighboring 2-D planes are interlinked by bridging 4,4'-bipyridine molecules,resulting in a novel 3D polymeric architecture.This 3D architecture represents a new topology with schlafli symbol (63.103)(63).The title complex shows high thermal stability (up to 350 °C).

Key words: zinc complex, coordination polymer, topology, thermal stability
