四溴代对苯二甲酸构筑的铜(Ⅱ)、钴(Ⅱ)配合物的合成及晶体结构

摘要

以四溴代对苯二甲酸(H2TBTA)及邻菲咯啉(phen)为配体,在相同反应条件下,得到2个金属-有机配合物{[Cu(phen)2(TBTA)].CH3OH· H2O}n (1)和[Co(HTBTA)2(phen)2] (2),并用元素分析、单晶X射线衍射、红外及热重分析对其进行了表征.配合物1和2显示出不同的结构,前者为一维链状结构而后者为单核零维结构.配合物1和2通过氢键作用及π-π相互作用显示出三维结构.%Two metal-organic complexes, namely {[Cu(phen)2(TBTA)] · CH3OH · H2O}n (1) and [Co(HTBTA)2(phen)2] (2) have been constructed from 2,3,5,6-tetrabromoterephthalic acid (H2TBTA) and 1,10-phenanthroline (phen) ligands in the same method, then characterized by elemental analysis, single-crystal X-ray diffraction, IR and thermal gravimetric analysis (TGA) techniques. Their crystal structures show different structure motifs: ID chain (1) and mononuclear molecule (2) metal-organic networks, respectively. The 3D structures of the 1 and 2 are constructed by hydrogen bonding and tt-tt interactions. CCDC: 854134, 1; 854133, 2.
