Abstract

The sandwich-shaped heterotopic trinuclear Ag+ complex Ag3 1⊙ 2 was exclusively formed from two different tris (thiazolyl) and hexa (thiazolyl) disk-shaped ligands, 1 and 2, with the aid of three Ag+ ions. The variable-temperature 1H NMR study on its complexation behavior revealed that metal-ligand exchanges between the two neighboring thiazolyl nitrogen donors of 2 take place at the three Ag+ centers in concert. Δ H⧧ and Δ S⧧ for the ...
