title: Mixed valence copper-sulfur clusters of highest nuclearity: a Cu8wheel and a Cu16nanoball.
abstract: Fully spin delocalized mixed valence copper-sulfur clusters, 1 and 2, supported by μ4-sulfido and NSthioldonor ligands are synthesized and characterized. Wheel shaped 1 consists of Cu2S2units. The unprecedented nanoball 2 can be described as S@Cu4(tetrahedron)@O6(octahedron)@Cu12S12(cage) consisting of both Cu2S2and (μ4-S)Cu4units. The Cu2S2and (μ4-S)Cu4units resemble biological CuAand CuZsites respectively.
