Solely on the basis of Raman spectra and quantum chemical calculations, the previously unknown cluster anion Si94- (structure shown) was characterized and its structure determined. The anion is formed as a component of solid phases by the thermal decomposition of alkali metal monosilicides.
Keywords: Ab initio calculations; Clusters; Raman spectroscopy; Silicon; Thermogravimetry.
