On the basis of Raman spectroscopic experiments and the computational assignment of the SN vibrations to small wavenumbers (640 ± 920 cm À1 ), the bonding in sulfur triimides is interpreted to be mainly electrostatic (b S + ÀN 7 À) rather than covalent (S(NR) 3 ).

Cu+ and Cu0 centers are found in the mixed valent compounds [Cu32As30(dppm)8] (structure shown in the picture) and [Cu26Te12(PEt2Ph)12] which formally contain a Cu3230+ or a Cu2624+ 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 Cu6 octahedron. The short Cu−Cu bonds do not result from d10–d10 interactions. dppm=methylene[(diphenyl)phosphine].
