Anion-directed supramolecular silver(i) complexes of an O2S2-macrocycle: cyclic oligomer and 2-D coordination polymers

Abstract

The effect of the anion on the assembly reactions of an O₂S₂-macrocycle L with AgX (X = NO₃⁻, BF₄⁻, CF₃SO₃⁻ or CF₃CO₂⁻) has been demonstrated to yield four supramolecular complexes (1–4) with different topologies: the exocyclic 2-D rectangular-grid coordination polymer [Ag(L)NO₃]_n (1), the endo-/exocyclic discrete cyclic tetramer [Ag₄(L)₄(BF₄)₂(CH₃OH)₂](BF₄)₂ (2), and the exocyclic 2-D coordination polymers [Ag(L)X]_n (3; X = CF₃SO₃ and 4; X = CF₃CO₂).
