coordination polymers, [M(2,6‐bip)2] (M = Zn (1), Ni (2)) and [Cu (tfbdc)(2,6‐bipH)2]•2H2O (3), were obtained with the similar solvothermal reaction systems of bivalent transition metal salt, 6‐(1H‐imidazol‐1‐yl)‐2(1H)‐pyridinone (2,6‐bipH) and 2,3,5,6‐tetrafluoroterephthalic acid (H2tfbdc). The three coordination polymers show different framework features, namely 3D (1), 2D (2) and 1D (3) structures, which are
三种金属-有机配位聚合物[M(2,6-bip)2 ](M = Zn(1),Ni(2))和[Cu(tfbdc)(2,6-bipH)2 ]•2H 2 O (3)是通过类似的二价过渡金属盐溶剂化反应体系6-(1H-咪唑-1-基)-2-(1H)-吡啶酮(2,6-bipH)和2,3,5获得的, 6‐四氟对苯二甲酸(H 2 tfbdc)。这三种配位聚合物表现出不同的骨架特征,即3D(1),2D(2)和1D(3)结构,这是由不同的单金属离子“节点”和“连接子”配位模式导致的。[ZnO 2 N 2]四面体在1和[氧化镍2 Ñ 4 ]八面体在2作为节点,选自Zn藻组成3和Ni d 2 SP 3分别混合轨道,而连接体,2,6-BIP,采用μ 2: η 1 η 1 η 0在1和μ 2:η 1 η 1 η 1在2位模式。PLATON计算表明1具有微孔结构,孔体积为14.2%。在3中,[CuO的2Ñ 2 ]平行四边形作为一个节点从铜衍生DSP
