摘　　要：本文报道了一种纯无机四核碘铜簇配合物Cu4I(4NH3)(4配合物1),并利用长链形双吡唑配体1,6-二(3,5-二甲基-1H-吡唑)-己烷与类似的四核碘铜簇构筑了一种五重穿插的配位聚合物(配合物2).拓扑网络分析表明:配合物1分子间通过弱I···H-N氢键形成了三维六连接bsn拓扑网络,而配合物2是一种五重穿插的dia拓扑网络.它们的发光主要归结为以碘铜簇为中心的激发态电荷跃迁(*CC).配合物1更大的斯托克斯位移和更低的发射能主要与Cu4I4配位单元间弱氢键和Cu4I4配位单元内部稍强的亲铜作用有密切关系.In this paper, a kind of CU414 （NH3）4 （1） was prepared. pure inorganic tetranuclear Copper（I）-Iodide complex A new kind of five-fold interpenetrated coordination polymer （2） constructed by long-chain bipyrazole ligand 1,6-bis （3,5-dimethyl-1H- pyrazol-4-yl）-hexane and the similar tetranuelear Copper（ I ）-Iodide units was synthesized by various methods. Topological analysis indicates that complex 1 exhibits a 3-D 6- connected bsn topology network supported by intermolecular weak I···H-N hydrogen bonds, and complex 2 shows five-interpenetrated dia topology. Their luminescence properties were ascribed to the cluster-centered charge transfer（ ＊CC ）. However, complex 1 shows larger Stoke＇s shift and lower energy emission than 2, which were assigned to the weak hydrogen bond and slightly stronger euprophilicity in 1.
