Abstract

Abstract: Reaction of carbene‐stabilized disilicon (1 ) with the lithium‐based dithiolene radical (2 . ) affords the first dianionic silicon tris(dithiolene) complex (3 ). Notably, the formation of 3 represents the unprecedented utilization of carbene‐stabilized disilicon (1 ) as a silicon‐transfer agent. The nature of 3 was probed by multinuclear NMR spectroscopy, single‐crystal X‐ray diffraction, and DFT computations. Abstract : Transfer market : The first six‐coordinate dianionic silicon tris(dithiolene) complex (see structure: purple Si, green S, blue N) was synthesized by utilizing carbene‐stabilized disilicon as a silicon‐transfer agent.
