Cu + and Cu 0 centers are found in the mixed valent compounds [Cu 32 As 30 (dppm) 8 ] (structure shown in the picture) and [Cu 26 Te 12 (PEt 2 Ph) 12 ] which formally contain a Cu 32 30+ or a Cu 26 24+ cluster core, respectively. Calculations of the electronic band structure show that a localization of the formal oxidation states is impossible. Both compounds contain a central Cu 6 octahedron. The short Cu−Cu bonds do not result from d 10 –d 10 interactions. dppm=methylene[(diphenyl)phosphine].
