Synthesis and crystal and solution structures of the 1 : 1 TMEDA complex of lithium thiocyanate, (LiSCN·TMEDA)n[TMEDA = Me2N(CH2)2NMe2]: a polymeric solid with Li+ ions linked by bifunctional linear SCN– ligands

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.
