摘要：

[Li(12-crown-4)2]+[Li({N(SiMe3)}2SPh)2]- 1 is the product of the reaction of Me3SiN = S = NSiMe3 with phenyllithium using 12-crown-4 as a donor and has an ion-separated structure which is unique for alkali metal sulphinamidino derivatives; at room temperature 1 undergoes a phase transformation, and a preliminary examination of this process by high-resolution solid-state Li-7 NMR spectroscopy shows, for the first time, the presence of three resolvable resonances.
