合成并表征了N,N‘-双(4-吡啶)亚烯(1R,2R)-二氨基环己烷(L1)和N,N′-bis(3-pyridyl)idene(1R,2R)-diaminocyclohexane(L2)两个非对映配体。研究了L1与Ag(I)离子、L2与Cd(II)离子的相互作用。{[Ag(L1)2](CF3SO3)·4H2O}n(1)的结构为波纹表面的(4,4)连通的二维片状结构,配合物[Cd(L2)2(NO3)(3H2O)]n·NO3·2H2O(2)形成节距为47.25°的无限大螺旋链。从链的顶部看,无限螺旋链形成了开口为∼1.2×1.2 nm的六角形纳米通道的壁。
Two diastereopure ligands, N,N′-bis(4-pyridyl)idene(1R,2R)- diaminocyclohexane (L1) and N,N′-bis(3-pyridyl)idene(1R,2R)-diaminocyclohexane (L2), have been synthesized and characterized. The interaction ofL1with Ag(I) ions andL2with Cd(II) ions has been investigated. The structure of {[Ag(L1)2](CF3SO3)·4H2O}n(1) exhibits a (4,4)-connected two-dimensional sheet with a corrugated surface and the complex [Cd(L2)2(NO3)(3H2O)]n·NO3·2H2O (2) forms an infinite single helical chain with a pitch of 47.25 Å. When viewed from the top of the chain, the infinite helical chain forms the wall of a hexagonal nanochannel with an opening of ∼1.2 × 1.2 nm.
