摘要：

The omega-cyano-eneamidolithium compound [Li{N(H)C(Me)=(H)CN}](n) obtained from Li[N(SiMe(3))Bu(t)] and an excess of MeCN, yields the crystalline dinuclear complex [Li{N(H)C(Me]=C(H)CN)}(py)(2)](2) 2a, containing a 12-membered macrocycle having four-coordinate lithium and a cis-arrangement of Me and H about the C=C bond; in [H-2(5)]pyridine solution compound 2a is fluxional, a transisomer 2b being implicated.
