aromatic dicarboxylate precursor, and the long-spanning dipyridyl ligand bis(4-pyridylmethyl)piperazine (4-bpmp) afforded three new coordination polymers, which were structurally characterized by single-crystal X-ray diffraction. [Cd(tere)(4-bpmp)(H2O)]n (1, tere = terephthalate) exhibits a simple non-interpenetrated 66 diamondoid 3D network with pentagonal bipyramidally coordinated cadmium ions. [Zn2(tere)(4-bpmp)2Cl2]n
摘要闭壳二价金属盐,对位芳族二羧酸盐前体与长跨度二吡啶基配体双(4-吡啶基甲基)哌嗪(4-bpmp)的水热反应提供了三种新型配位聚合物,其结构特征为单-晶体X射线衍射。[Cd(tere)(4-bpmp)(H2O)] n(1,tere =对苯二甲酸酯)显示具有五角双锥体配位的镉离子的简单非互穿的66类金刚石3D网络。[Zn2(tere)(4-bpmp)2Cl2] n(2)具有四面体配位的锌原子,表现出一种极为罕见的1D + 1D→1D平行互穿的穿线环聚轮烷结构。通过使用1,4-苯二乙酸(1,4-phda)配体扩展对位芳族二羧酸酯侧链臂生成[Zn(1,4-phda)(4-bpmp)(H2O)2]·2H2O} n(3 ),该图显示了一个简单的堆叠式(4,4)网格结构。还讨论了这些材料的发光特性。
