Abstract

Structurally characterized lithium pentadienyls are very rare. We report the molecular structures of two lithium pentadienyls, [(pmdeta)Li{1-(R ₃Si)C₅H₆}] (3) and [(pmdeta)Li{1,5-(R ₃Si)₂C₅H₅}] (4) (R₃Si = Me₂(NMe₂)Si, pmdeta = N,N,N′,N″,N″- pentamethyldiethylenetriamine). In 3, the pentadienyl carbons adopt an η³ coordination mode, whereas in 4 η¹ coordination is found. The origins of the different coordination modes are discussed.
