| Abstract: | 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-sulfonatothiacalix4]arene (H<,4>TCAS<'4->): Ln<,2>(PNO)<,2>(H<,2>O)<,10> (H<,2>TCAS)<,2>]· Ln<,2>(H<,2>TCAS)<,2>(H<,2>O)<,6>(MeOH)<,2>]·2MeOH·12H<,2>O (Ln = La, 1; Nd, 2).Crystal data for complex 1: C<,31>H<,51>La<,2>NO<,33>S<,8>, M<,r> = 1500.03, triclinic system, P<,1><'-> space group, with a = 11.732(2), b = 15.007(3), c = 15.262(3) (A), a = 78.05(3), β = 80.77(3), y = 83.89(3)°, Z = 2, V= 2587.3(9) (A)<'3>, D<,c>= 1.925 g/cm<'3>,μ = 2.051 mm<'-1>, F(000) = 1500, the final R = 0.0300 and wR = 0.0823; and those for complex 2: C<,31>H<,51>Nd<,2>NO<,33>S<,8>, M<,r> = 1510.69, triclinic system, P<,1><'-> space group, with a = 11.719(2), b = 14.941(3), c=15.157(3) A, a = 78.03(3), β = 80.84(3), y = 83.95(3)°, Z = 2, V= 2555.9(9) A<,'3>, D<,c>= 1.963 g/cm<'3>,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'-μ<,2> mode.The dinuclear ions are shrouded by two H<,2>TCAS<'6-> ions through coordination interactions and hydrogen bonds.The other coordination mode of Ln ions is a zigzag 1D chain linked by up-down H<,2>TCAS<'6-> ions.By the coordination capsules, the complexes form 2D zigzag-ladder structure coordination polymers. |
