合成了三个新的金属有机骨架化合物[Cd(TiA)(H2O)(2)](N)(1)，[Cu(TiA)(H2O)(2)](N)(2)和{[Zn-3(CTIA)(2)中心点(H2O)(8)]中心点2H(2)O}(N)(3)(TiA(2-)=5-(1H-1，2，3-三唑-1-基)间苯二甲酸酯，CTIA(3-)=5-(4-羧基-1H-1，2)，在水热条件下合成了(3-三唑-1-基)间苯二甲酸酯)，并对其进行了表征。单晶X-射线衍射分析表明，化合物1和2具有相似的2D(6，3)拓扑网络层，并通过氢键相互作用将这些网络层连接起来，形成三维超分子结构。络合物3显示了一种独特的一维梯形链结构，其中平行排列的锌配位链通过包含锌中心的SBUS(SBUs：二级建筑单元)连接在一起。在2-300K范围内的磁性测量表明，配合物2中相邻的铜离子之间存在反铁磁性相互作用。在室温下，配合物1和3在固态下表现出很强的发光。(C)2012爱思唯尔有限公司。保留所有权利。
Three new metal-organic frameworks (MOFs), formulated as [Cd(tia)(H2O)(2)](n) (1), [Cu(tia)(H2O)(2)](n) (2) and {[Zn-3(ctia)(2)center dot(H2O)(8)]center dot 2H(2)O}(n) (3) (tia(2-) = 5-(1H-1,2,3-triazol-1-yl) isophthalate, ctia(3-) = 5-(4-carboxylato-1H-1,2,3-triazol-1-yl) isophthalate) have been synthesized under hydrothermal conditions and characterized. Single-crystal X-ray diffraction analysis reveals that complexes 1 and 2 show similar common 2D (6, 3) topology network layers and these layers are further connected by H-bonding interactions to form 3D supermolecular structures. Complex 3 displays a unique 1D ladder-like chain structure, in which parallel arrangements of Zn1 coordination chains are linked by SBUs (SBUs: Secondary Building Units) containing the Zn2 center. Magnetic measurements in the range 2-300 K have shown antiferromagnetic interactions among the adjacent copper ions in complex 2. Complexes 1 and 3 exhibit strong luminescent emissions in the solid state at room temperature. (c) 2012 Elsevier Ltd. All rights reserved.
