Metal‐directed self‐assembly approaches led to the formation of two novel boat‐shaped palladium(II)‐based metallacalixarenes 1 (1 a, 1 b and 1 c) and 2 (2 a, 2 b and 2 c), by using the two new ligands 2,6‐bis(1H‐naphtho[2,3]imidazol‐1‐yl)pyridine (L¹) and 1,3‐bis(1H‐naphtho[2,3]imidazol‐1‐yl)benzene (L²) with cis‐coordinated Pd^II precursor (tmeda)Pd(ONO₂)₂ (tmeda=N, N, N′, N′‐tetra‐methylethylenediamine), repectively. All complexes with different counterions were systematically characterized in solution, and their structures were determined by X‐ray single crystallography analyses in the solid state. The crystal architectures were subtly regulated among different anions through two types (inter‐ and intra‐)molecular C−H hydrogen bonding interactions and other weak interactions. The anion complexation with the two metal‐assembled anion receptors were further investigated in solution.

使用吡啶基或苯基桥联的二萘并咪唑对基于钯（II）的金属铝芳烃进行自组装和CH-H·⋅·⋅氢键键合

金属定向自组装方法通过使用以下方法形成了两种新型的船形钯（II）基金属lacalixarenes 1（1 a，1 b和1 c）和2（2 a，2 b和2 c）。两个新的配体2,6-双（1H-萘[2,3]咪唑-1-基）吡啶（L ¹）和1,3-双（1H-萘[2,3]咪唑-1-基）苯（L ²）与顺式配位的Pd ^II前体（tmeda）Pd（ONO ₂）₂（tmeda = N，N，N'，N'-四甲基乙二胺）。所有具有不同抗衡离子的配合物都在溶液中进行了系统表征，并通过固态X射线单晶分析确定了它们的结构。通过两种类型的（分子间和分子内）CHH氢键相互作用和其他弱相互作用，晶体结构在不同阴离子之间得到了微妙的调控。在溶液中进一步研究了阴离子与两种金属组装的阴离子受体的络合。
