Anion–ligand interaction in binuclear cyclic dimer complex of a tribenzo-S2O2 macrocycle with silver(I) picrate

Add time:09/29/2019    Source:infona.pl

From the reaction of tribenzo-S 2 O 2 macrocyclic ligand (L 1 ) and silver picrate (AgPic), a unique binuclear complex [Ag 2 (L 1 ) 2 (Pic) 2 ] (1) has been obtained. The species 1 has been characterised by single-crystal X-ray diffraction analysis providing a definitive proof of its cyclic dimer structure as well as the anion–ligand π–π stacking interactions between L 1 and Pic − . The result of a comparative NMR experiment suggests that the solid structure of 1 is also retained in solution.
