Bioinspired Enhancement of Superexchange: From 1,3,5-Trihydroxybenzene-Bridged to 1,3,5-Trimercaptobenzene-Bridged Trinuclear Copper(II) Complexes
An unprecedented trinucleating ligand with a central 1,3,5-trimercaptobenzene unit and its trinuclear Cu-3(II) complex are presented. The high covalency of the difficult-to-realize Cu-II-SR bond provides an order of magnitude increase in the superexchange interaction in comparison to its oxygen analogue.
