摘　　要：Metallo-supramolecular architectures that are constructed by coordination-driven self-assembly have received tremendous attention on account of their diverse yet molecular-level precise structures and broad applications.Of particular,metal cations and counter anions are fundamentally important in terms of self-assembly,characterization and property;however,their effects on the structural stabilities of metallo-supramolecular architectures have seldom been investigated.To address this issue,herein,a series of octahedral metallo-cages that are capable of tolerating with five metal cations(Pd^(2+),Cu^(2+),Ni^(2+),Co^(2+)and Zn^(2+)),and five counter anions(ClO_(4)^(–),OTf^(–),BF_(4)^(–),NTf_(2)^(–)and NO_(3)^(–))are constructed by the coordination-driven self-assembly of a well-designed tritopic isoquinoline-based ligand with corresponding metal salts.Structural stability studies show that metal cations and counter anions play a critical role in the stability of the resulting cages depending on their coordination abilities and stacking manners.This work provides deep insights in the ever-diversifying field of metallo-supramolecular chemistry,and will enable us to design more sophisticated assembled structure with desired function.
