摘要
以四溴代对苯二甲酸(H2TBTA)与2,2′-联吡啶(2,2′-bipy)为配体,与硝酸铜在水和甲醇混合溶剂中合成了1个一维铜配合物{[Cu(2,2′-bipy)(TBTA)(H2O)].H2O}n,并通过元素分析、红外分析、热重分析、X-射线粉末衍射和X-射线单晶衍射对其进行了表征。该配合物属于正交晶系,空间群为Pna21,a=1.399 9(11)nm,b=0.929 3(7)nm,c=1.557 9(11)nm,V=2.027(3)nm3,Z=4,R1=0.053 5。中心Cu(Ⅱ)离子处于一个五配位环境中,且在配合物中存在着π-π相互作用和氢键作用。热重分析表明该配合物在203℃开始发生分解。
Assembly of 2,3,5,6-tetrabromoterephthalic acid 3H20 in H20/CH30H solution using the layered diffusion (H2TBTA) with 2,2'-bipyridine (2,2'-bipy) and Cu(NO3)2 method affords a 1D coordination polymer {[Cu (2,2'- bipy) (TBTA)(H20)] .H2O},, which has been characterized by elemental analysis, IR spectroscopy, thermogravi- metric analysis, powder X-ray diffraction analysis and single-crystal X-ray diffraction. Complex crystallizes in orthorhombic system, space group Pna21 with a=1.399 9(11) nm, b=0.929 3(7) nm, c=1.557 9(11) nm, V=2.027(3) nm3, Z=4, R1=0.053 5. The central Cu (11) ion is five-coordinated, and there are π-π interactions and H-bonding interactions in the complex. The TG analysis shows that the complex is stable below 203 ℃. CCDC: 870487.
