Solvent-dependent supramolecular isomers of a tripodal ligand incorporating two para-pyridylmethyl arms, N-naphthylmetyl-N,N-bis(4-pyridylmethyl)amine (L), are reported. A combination of L and copper(II) hexafluoroacetylacetonate, Cu(hfac)₂, in methanol afforded a cyclic dimer complex [Cu₂(L)₂(hfac)₄]·CH₃OH (1). In chloroform/methanol, the same reaction furnished an infinite one-dimensional (1D) complex {[Cu₂(L)₂(hfac)₄]·2CHCl₃}_n (2). When the cyclic dimer 1 was immersed in chloroform/ether, its transformation to the 1D coordination polymer 2 was observed in an single-crystal to single-crystal manner. In silver(I) triflate complexations, three supramolecular isomers (3–5) were isolated. In chloroform/methanol, a multichannel-type three-dimensional (3D) coordination polymer {[Ag(L)](CF₃SO₃)·0.5CHCl₃}_n (3) was isolated. In isomer 3, the Ag atom link L ligands alternately to form a helix, and these are linked by Ag–Ag contacts to generate an etb topology. In acetonitrile/methanol, a multichannel-type 3D coordination polymer {[Ag(L)](CF₃SO₃)·CH₃CN}_n (4) was isolated. In isomer 4, six Ag atoms and six L ligands form an Ag₆L₆ hexagonal unit, and these are linked via Ag–Ag contacts, resulting in a pcu-h topology. In toluene/methanol/acetonitrile, a cross-linked ladder-type coordination polymer {[Ag₄(L)₄(CF₃SO₃)₂](CF₃SO₃)₂·3(toluene)}_n (5) was obtained. The isomer 5 is composed of two types of ladders crossed showing a new topology. Considering the formation of the (π–π)-(Ag–Ag)-(π–π) unit in 3–5, it is suggested that the anion–solvent interaction could be a major reason.

超分子异构体的溶剂依赖性形成以及从环状二聚体络合物到一维配位聚合物的单晶向单晶转变

报道了结合有两个对-吡啶基甲基臂，N-萘基甲基-N，N-双（4-吡啶基甲基）胺（L）的三脚架配体的溶剂依赖性超分子异构体。的组合大号和铜（II）六氟乙酰丙酮，铜（HFAC）₂，在甲醇中，得到的环状二聚体复合物[Cu ₂（大号）₂（HFAC）₄ ]·CH ₃ OH（1）。在氯仿/甲醇中，相同的反应提供了无限的一维（1D）络合物{[Cu ₂（L）₂（hfac）₄ ]·2CHCl ₃ } _n（2）。当将环状二聚体1浸入氯仿/醚中时，以单晶至单晶的方式观察到其向1D配位聚合物2的转变。在银（I）三氟甲磺酸酯complexations，三分超分子异构体（3 - 5）中分离得到。在氯仿/甲醇中，分离出多通道型三维（3D）配位聚合物{[Ag（L）]（CF ₃ SO ₃）·0.5CHCl ₃ } _n（3）。在异构体3中，Ag原子连接L配体交替形成螺旋，它们通过Ag-Ag接触连接以生成etb拓扑。在乙腈/甲醇中，分离出多通道型3D配位聚合物{[Ag（L）]（CF ₃ SO ₃）·CH ₃ CN} _n（4）。在异构体4中，六个Ag原子和六个L配体形成一个Ag ₆ L ₆六角形单元，它们通过Ag-Ag接触连接，形成pcu-h拓扑。在甲苯/甲醇/乙腈中，交联的梯型配位聚合物{[Ag ₄（L）₄得到（CF ₃ SO ₃）₂ ]（CF ₃ SO ₃）₂ ·3（甲苯））_n（5）。异构体5由交叉显示新拓扑的两种类型的梯子组成。考虑到3 – 5中（π–π）-（Ag–Ag）-（π–π）单元的形成，建议阴离子与溶剂的相互作用可能是主要原因。
