Angew Chem Int Ed Engl. 1998 Sep 18;37(17):2359-2361. doi: 10.1002/(SICI)1521-3773(19980918)37:17<2359::AID-ANIE2359>3.0.CO;2-G.

Abstract

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.
