摘要
Two isomorphous 2D zigzag-ladder structure coordination polymers containing coordination supramolecular capsules are reported,which are built by trivalent lanthanide ions,pyridine N-oxide（PNO） and p-sulfonatothiacalix[4]arene（H4TCAS4-）：[Ln2（PNO）2（H2O）10？（H2TCAS）2].[Ln2（H2TCAS）2（H2O）6（MeOH）2].2MeOH.12H2O（Ln = La,1;Nd,2）.Crystal data for complex 1：C31H51La2NO33S8,Mr = 1500.03,triclinic system,P 1 space group,with a = 11.732（2）,b = 15.007（3）,c = 15.262（3）,α = 78.05（3）,β = 80.77（3）,γ = 83.89（3）°,Z = 2,V = 2587.3（9）3,Dc = 1.925 g/cm3,μ = 2.051 mm-1,F（000） = 1500,the final R = 0.0300 and wR = 0.0823;and those for complex 2：C31H51Nd2NO33S8,Mr = 1510.69,triclinic system,P1 space group,with a = 11.719（2）,b = 14.941（3）,c = 15.157（3）,α = 78.03（3）,β = 80.84（3）,γ = 83.95（3）°,Z = 2,V = 2555.9（9）3,Dc = 1.963 g/cm3,μ = 2.436 mm-1,F（000） = 1512,the final R = 0.0493 and wR = 0.1267.There are two coordination environments of lanthanide ions.One is bridged by two PNO molecules forming a dimeric Ln ion in the O,O’-μ2 mode.The dinuclear ions are shrouded by two H2TCAS6-ions through coordination interactions and hydrogen bonds.The other coordination mode of Ln ions is a zigzag 1D chain linked by up-down H2TCAS6-ions.By the coordination capsules,the complexes form 2D zigzag-ladder structure coordination polymers.
