Abstract

The self-assembly of Ag(I) ions with 3,5-dimethyl-4-amino-1,2,4-triazole (L₁) and 4-salicylideneamino-1,2,4-triazole (L₂) gave two novel complexes, [Ag₄(μ₂-L₁) ₆][Ag₄(μ₂-L₁)₆(CH ₃CN)₂](ClO₄)₈·2H ₂O (1) and [Ag₄(μ₂-L₂) ₆(CH₃CN)₂](AsF₆)₄· 2H₂O (2), both of which contain tetranuclearic clusters constructed via Ag(I) ions and six N1,N2-bridged triazoles with a Ag₄N ₁₂ core. When 4-(6-amino-2-pyridyl)-1,2,4-triazole (L₃) was employed, {[Ag₄(μ₂-L₃) ₄(μ₃-L₃)₂](CF₃SO ₃)₄· H₂O}_n (3), {[Ag ₄(μ₂-L₃)₄(μ₃-L ₃)₂](ClO₄)₄}_n (4), and {[Ag₄(μ₂-L₃)₂(μ₃- L₃)₄](PF₆)₄·CH ₃CN·0.75H₂O}_n (5) were isolated. 3 and 4 are 1D polymers, while 5 is a 2D polymer. 1D and 2D coordination polymers are constructed via the self-assembly of Ag₄N₁₂ cores as secondary building units (SBUs). The connection of these SBUs can be represented as a ladderlike structure for 1D polymers and a 4.8² net for 2D polymers. Electrospray ionization mass spectrometry measurements and NMR ( ¹H and ¹³C) studies demonstrate that the tetranuclear SBU retains its integrity and the coordination polymers decompose into the tetranuclear Ag₄N₁₂ core in solution. 2 exhibits blue emission in the solid state and green emission in solution at ambient temperature. Strong blue fluorescence for complexes 3-5 in the solid state can be assigned to the intraligand fluorescent emission.
