Abstract
Treatment of hexasilylfulvene (4) with lithium metal in, tetrahydrofur an yields yellow crystals of the dilithium hexasilylfulvene dianion (5 ). The dilithium hexasilylfulvene dianion (5) has a monomeric structur e and forms a contact ion pair (bis-CIP) in the crystals. One of the l ithium atoms is located above the center of the five-membered ring, wh ereas the other one is bonded to the exocyclic carbon atom. The bis-CI P structure determined by X-ray crystallography is maintained in solut ion.
