Abstract

Abstract : The synthesis, structure and properties of highest nuclearity spin delocalized mixed valence (MV) copper–sulfur clusters, a Cu8 nanowheel and a Cu16 nanoball containing Cu2 S2 and (μ4 -S)Cu4 units resembling CuA and CuZ sites, respectively, are reported. Abstract : Fully spin delocalized mixed valence copper–sulfur clusters, 1 and2, supported by μ4 -sulfido and NS thiol donor ligands are synthesized and characterized. Wheel shaped1 consists of Cu2 S2 units. The unprecedented nanoball2 can be described as S@Cu4 (tetrahedron)@O6 (octahedron)@Cu12 S12 (cage) consisting of both Cu2 S2 and (μ4 -S)Cu4 units. The Cu2 S2 and (μ4 -S)Cu4 units resemble biological CuA and CuZ sites respectively.
