Molecular botanical garden: assembly of supramolecular silver(I) and mercury(II) complexes of NS 2 -donor macrocycles with flower-, leaf- and tree-shaped structures

Isomeric NS2macrocycles (ortho: L1, meta: L2 and para: L3) were synthesised and their complexes (1–4) were isolated; L1 and L2 afforded flower-type cyclic hexamer (1) and tree-shaped 3 : 4 (M/L) complex (2), respectively, in the reactions of AgPF6, meanwhile L2 and L3 afforded a respective leaf-like 1D chain (3a) and a brick-wall type 2D network (4) in the reactions of HgBr2.
