Three coordination polymers of [(NiL1)3(TCBA)2] (1), [(NiL2)3(TCBA)2] (2), and [(NiL3)3(TCBA)2] (3) have been constructed using azamacrocyclic Ni(II) complexes [NiL1](ClO4)2/[NiL2](ClO4)2/[NiL3](ClO4)2 and TCBA3- as building blocks (L1 = 3,10-bis(2-fluorobenzyl)-1,3,5,8,10,12-hexaazacyclotetradecane; L2 = 3,10-bis(3-fluorobenzyl)-1,3,5,8,10,12-hexaazacyclotetradecane; L3 = 3,10-bis(4-fluorobenzyl)-1
[(NiL 1)3(TCBA)2 ](1),[(NiL 2)3(TCBA)2 ](2)和[(NiL 3)3(TCBA)2 ](3)的三种配位聚合物具有使用氮杂大环Ni(II)配合物[NiL 1 ](ClO 4)2 / [NiL 2 ](ClO 4)2 / [NiL 3 ](ClO 4)2和TCBA 3-作为结构单元(L 1= 3,10-双(2-氟苄基)-1,3,5,8,10,12-六氮杂环十四烷; L 2= 3,10-双(3-氟苄基)-1,3,5,8,10,12-六氮杂环十四烷;L 3 = 3,10-双(4-氟苄基)-1,3,5,8,10,12-六氮杂环十四烷; TCBA 3-=三(4-羧基-苄基)胺。X射线衍射分析的结果表明,1显示2D Borromean结构,2和3形成2D层结构,并且2D层通过2和C–H··之间的层间F ·· F相互作用进一步连接。· 3中的F相互作用生成两个3D多孔
