摘要 在水-甲醇混合溶剂体系中,以四溴代对苯二甲酸(H2TBTA)及邻菲咯啉(phen)为配体,得到一个超分子配合物{[Cd(phen)2(TBTA)](H2O)(CH3OH)}n(1),并用元素分析、X-射线单晶衍射及热重分析对其进行了表征。结果分析表明,配合物1属于三斜晶系,P-1空间群,a=9.4774(7),b=10.7306(8),c=17.1542(13),V=1653.4(2)3,Z=2,Dcalc=2.014 mg/mm3,R1[I>2σ(I)]=0.0372,wR2(all data)=0.0750。配合物1通过氢键作用及π-π相互作用构筑成三维超分子。 A supramolecular polymer { [ Cd (phen) 2 (TBTA) ] ( H2 O) ( CH3 OH) I n ( 1 ) was constructed from 2,3,5, 6 - tetrabromoterephthalic acid (H2TBTA) and 1,10 - phenanthroline (phen) ligands in a water - methanol solution, and then characterized by elemental analysis, single -crystal X -ray diffraction and thermal gravimetric analysis (TGA) tech- niques. The experiment showed that crystal data of complexe 1 was triclinic, P- 1, a =9.4774(7) A, b = 10.7306(8) A, c =17. 1542(13) A, V= 1653.4(2) A3, Z =2, De,at =2.014 mg/mm3, R1 [I 〉 2σ-(1).] =0.0372, and wR2 (all data) = 0. 0750. The 3D supramolecular structure of the complexes 1 was constructed by hydrogen bonding and/or π-π interactions.
