摘要
Stable, deep-blue neutral radicals [(Me3SiN) P (μ 3-NtBu)3{μ3-Li(thf)}3X] (X = Br, I) with distorted cubic structures are obtained by the oxidation of [{Li 3[P(NtBu)3(NSiMe3)]}2] with halogens in THF (see picture). The cubes comprise the radical dianion [P(NtBu)3(NSiMe3)].2-. two Li+ ions, and a molecule of LiX. Solvation in very dilute THF solution releases (thf)3LiX and generates the cyclic radical monoanion [(Me 3SiN)(tBuN) P (μ-NtBu)2Li(thf)2] .-.
