Abstract

High-pressure conditions afford unique all-hydrido hypervalent complexes [SiH 6] 2- in the crystalline hydridosilicates A 2SiH 6 (A=K, Rb). Compared to normal-valent silanes the Si-H bond appears considerably enlarged, by about 0.15 Å. Accordingly, Si-H stretching frequencies are drastically reduced, by about 400-500 cm -1, thus reflecting the weakness of a hypervalent Si-H bond.
