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.
