Construction of modular Pd/Cu multimetallic chains via ligand- and anion-controlled metal–metal interactions

Abstract

The presence of Pd⋯Cu and Pd⋯Pd interactions as well as the order of metal atoms in a chain held by a modular polynucleating ligand is controlled by the coordinating ability of the anions, leading to selective formation of bi- and tetranuclear Pd/Cu and Pd₄ chains. Metal–metal cooperative reactivity in these complexes was tested in Ar–O bond formation and alkyne activation.
