【摘要】 近年来,功能配合物材料因具有迷人的拓扑结构和潜在的应用前景已经引起人们的关注,醚氧二羧酸作为一种柔性多齿桥联配体,已被广泛应用于构筑金属有机配合物[1,2]。本文以2,2-二羧酸二苯甲醚(H2oba)和1,2-二(4-吡啶基)乙烯(bpe)为构件单元,过渡金属Ni(Ⅱ)为中心离子,在水热条件下,采用不同的摩尔比合成了两个金属配合物[Ni(oba)(bpe)]n(1)和{[Ni(oba)(bpe)1.5]·4H2O}n(2)。在配合物1中,oba配体中的羧基采用双单齿桥联模式连接紧邻的四个金属Ni(II)离子形成一维链状结构,bpe配体桥联相邻的一维链,形成一个二维网状结构(图1a)。而在配合物2中,oba配体采用三齿配位模式作为封端基团,bpe配体桥联相邻的金属Ni(II)离子,形成一个二维网状结构(图1b)。此外,还研究了配合物1-2的磁学性质。更多还原

【Abstract】 Functions of complex material are currently of interest owing to their intriguing topology structures and potential applications. 2,4-oxybis(benzoic acid), as a flexibility multidentate bridging ligand, has been widely used constructing metal complexes. In this work, adjusting the materials of molar ratio of different, two metal Ni(II) complexes [Ni(oba)(bpe)]n(1) and {[Ni(oba)(bpe)1.5]·4H2O}n(2)(H2oba = 2,4-oxybis(benzoic acid), bpe = 1,2-Bis(4-pyridyl)ethylene) have been synthesized under hydrothermal conditions. In 1, the carboxyl group of oba ligand adopt two monodentate bridging mode connected the adjacent Ni(II) ions to afford a 1D chain, further the adjacent chains are interconnected though bpe ligands to form a 2D network(Fig. 1a). However, in 2, the oba ligand adopt tridentate coordination mode as capping group, the bpe ligands connected the adjacent Ni(II) ions to afford a 2D network(Fig. 1b). Furthermore, the magnetic properties for 1-2 have also been investigated.更多还原
