Abstract
Reactions of 2-bis (trimethylsilyl) methylpyridine, (1), with LiBun in hexane–diethyl ether, and LiBun in tetrahydrofuran followed by CuCl, yields thermally robust binuclear complexes [{2-(Me3Si)C2(M)C5H4N}2] for M = Li and M = Cu respectively in which the metal is not involved in electron deficient bonding, being bound by Cα of one ligand and the nitrogen of a centrosymmetrically related ligand and has a close metal contact [M ⋯ M 2.560(9)(Li) and 2.412(1)Å(Cu)].Keywords
