Networking of Tribenzo-O₂S₂-Macrocycles with Mercury Thiocyanate: Effect of Macrocyclic Isomers

Tribenzo-O2S2-macrocyclic isomers incorporating a xylyl group in the ortho (o-L), meta (m-L), and para (p-L) positions were employed to examine the effect of ligand isomers on supramolecular networking assembly with mercury(II) thiocyanate. o-L and p-L afforded 1-D linear [Hg2(o-L)(SCN)4]n (1) and 1-D zigzag [Hg(p-L)(SCN)2]n (3) coordination polymer networks, respectively, while m-L gave a brick-wall type 2-D network polymer of type [Hg2(m-L)(SCN)4]n (2). All three polymeric structures show different thiocyanate binding motifs.
