Title: The effect of anion–ligand π-stacking interaction on silver(I) extraction by thiaoxa-macrocycles: A search for the evidences by X-ray and NMR approaches
Authors: Song, Mi Ryoung1, Lee, Ji-Eun1, Lee, So Young1, Seo, Joobeom1, Park, Ki-Min1, Lee, Shim Sung sslee@gsnu.ac.kr

Subjects: Silver, Extraction (Chemistry), Ions, Intermediates (Chemistry)
Abstract: Abstract: S2O x macrocyclic ligands with (L 1: x =3 and L 2: x =4) and without (L 3: x =3 and L 4: x =4) dibenzo-subunit were employed as extractants to clarify the anion–ligand interaction on the extraction efficiency of soft metal picrates. All of the ligands shows silver(I) selectivity and the silver picrate was more extractable with L 1 and L 2 when compared with L 3 and L 4. From the X-ray and NMR data, the enhanced extractability for the silver picrate by L 1 and L 2 was revealed due to the additional stabilization of the complexes, [Ag(L)picrate], by anion–ligand π–π interaction between the picrate ion and one benzo-subunit in the ligand. Such anion–ligand interaction would give a valuable hint for the molecular design of new extractants for the soft metal ions including silver(I). [Copyright &y& Elsevier]
