摘要

The radical [N(CH₃)₃]⁺ has been detected at room temperature by electron paramagnetic (EPR) in γ-irradiated [NH(CH₃)₃]₂ SnCl₆ crystals. The EPR spectrum of this radical can be analysed by assuming that the three methyl groups execute rapid rotations, while the radical as a whole remains fixed in orientation in the cubic crystal lattice. [SnX₆]^3- (X = Cl, Br) radicals have been detected by EPR at liquid-nitrogen temperatures in γ- or u.v.-irradiated [NH(CH₃)₃]₂SnX₆ crystals. These octahedral [SnX₆]^3- complexes could be statically-distorted Jahn-Teller species.
