Stable, deep‐blue neutral radicals [(Me 3 SiN)P(μ 3 ‐N t Bu) 3 {μ 3 ‐Li(thf)} 3 X] (X=Br, I) with distorted cubic structures are obtained by the oxidation of [{Li 3 [P(N t Bu) 3 (NSiMe 3 )]} 2 ] with halogens in THF (see picture). The cubes comprise the radical dianion [P(N t Bu) 3 (NSiMe 3 )] .2− , two Li + ions, and a molecule of LiX. Solvation in very dilute THF solution releases (thf) 3 LiX and generates the cyclic radical monoanion [(Me 3 SiN)( t BuN)P(μ‐N t Bu) 2 Li(thf) 2 ] .− .
