With CoBr2, the compound [Co(μ-Br){C(SiMe3)2(SiMe2NMe2)}]2 (7) was obtained. The reaction between the lithium compound Li(THF)2{C(SiMe3)2(SiMe2OMe)} and MnCl2 in THF gave [Mn(THF)(μ-Cl){C(SiMe3)2 (SiMe2OMe)}]2 (5). The crystal structures of compounds 4, 5, 6 and 7 were determined. Compounds 4 and 5 are the first manganese analogues of Grignard reagents containing Mn-C σ-bonds to be characterised in the solid state. © 2002 Elsevier Science B.V.
