Abstract

The anhydrous complex (LiSCN·TMEDA)n(1)[TMEDA = Me2N(CH2)2NMe2] has been synthesised by a novel in situ route from solid NH4SCN and BunLi in TMEDA/hexane, and shown to have a polymeric chain crystal structure with Li–N[graphic omitted]CS Li repeat units; in hydrocarbon solvents, however, (1) adopts a dimeric, purely N–Li bridged structure.
