Anion−π-Interaction-Directed Self-Assembly of Ag(I) Coordination Networks

Reactions of AgX with 2,4,6-tri(2-pyridyl)-1,3,5-trazine (tpt) yielded three 3D highly symmetric isostructural coordination polymers (X = ClO4-, BF4-, and PF6-) and a dimer (X = CF3COO-), respectively. In the coordination polymers, anion−π interactions are found between the multiatomic anions and tpt ligands. Systematic variation including synthetic methods, ratios of reactants, and solvents provides synthetic evidence proving that anion−π interactions play a decisive role in assembly of the coordination polymers

In Situ Formed Guanidinium Cations as Templates To Direct Fabrication of Honeycomb-like CuCN Networks

The solvothermal reaction of CuSCN and 1,2-bis(diphenylphosphino)ethane (dppe) in mixed solvents acetonitrile/n-hexane/(methanol or ethanol) gave a honeycomb-like guanidinium cyanocuprate [C(NH2)3)]·[Cu2(CN)3]. The in situ formed cations C(NH2)3+ act as templates to direct the formation of the CuCN network in which multiple weak N−H····N/C hydrogen interactions potentially exist between the cations C(NH2)3+ and the {CuCN}6 rings
