The alkaline‐earth metal silanides, ( t Bu 3 Si) 2 Be and ( t Bu 3 Si) 2 Mg, have been synthesized from the reaction of the sodium silanide t Bu 3 SiNa with BeCl 2 in Bu 2 O and MgBr 2 in THF. The bissupersilylmagnesium THF adduct [( t Bu 3 Si) 2 Mg(THF) 2 ] reacts with GaBr 3 in benzene at ambient temperature to form t Bu 3 SiGaBr 2 and t Bu 3 SiMgBr(THF). The structures of bissupersilyl silanides, ( t Bu 3 Si) 2 Be and ( t Bu 3 Si) 2 Mg(THF) 2 , and the Grignard analogue, t Bu 3 SiMgBr(THF), have been determined by X‐ray structure analysis.
