Dalton communications. Synthesis and structure of a stable selenodiimide complex
Abstract
The stable selenodiimide complex SnCl4[(ButN)2Se]1 has been prepared from Se[NBut(SiMe3)]2 and SnCl4, and also by treating the unstable (ButN)2Se (obtained from NButH2 and SeCl4) with SnCl4; the crystal structure of 1·2thf indicates appreciable SeN double-bond character [171.0(3) pm] but also shows that the selenium atom is unexpectedly co-ordinated by the two tetrahydrofuran (thf) oxygens.
