Bis[1,3-bis(trimethylsilyl)allyl]cobalt(II), a stable electron-deficient allyl complex
Abstract:The title compound, bis[(1,2,3-)-(2E)-1,3-bis(trimethylsilyl)prop-2-enyl]cobalt(II), [Co(C9H21Si2)2], is a homoleptic allyl complex with 3-bound ligands. The Co—C distances range from 1.996 (3) to 2.096 (3) Å and the allyl ligands adopt staggered, nearly parallel, arrangements around the Co atom. The trimethylsilyl groups are in syn–anti conformations; the steric shielding they provide to the metal is probably responsible for the thermal stability of the compound.
