Diamidocarbene-derived palladium and nickel–sulfur clusters

Abstract

Novel palladium and nickel–sulfur clusters were synthesized using a diamidocarbene-derived carbon disulfide ligand. Structural characterization revealed a tetranuclear metal–sulfur cluster geometry with each metal center exhibiting square-planar coordination. The ligand was redox-active, accommodating oxidation states ranging from 0 to −2.
