The reaction of bismuth trihalides with the bulky alkali metal silanides [(THF) 3 LiSi(SiMe 3 ) 3 ] and [(THF) 2 NaSi(CMe 3 ) 3 ] affords the cyclotetrabismuthanes (RBi) 4 1 and 3 , the alkali metal bismuthanides [Li(THF) 4 ][Bi{Si(SiMe 3 ) 3 } 2 ] ( 2 ) and Na(THF) 3 [Bi{Si(CMe 3 ) 3 }] 2 ( 4 ) and the bismuthanediide Na 3 (THF) 14 [Na 21 {BiSi(CMe 3 ) 3 } 12 ] ( 5 ). Compound 2 features a two‐coordinate bismuth atom. The core of 5 is a Bi 12 icosahedron which is face‐capped by 20 sodium atoms. The cluster is filled with a sodium atom. All structures were confirmed by single crystal X‐ray crystallography. In addition, the bismuthanides and bismuthanediides were investigated by quantum chemical calculations.
