Syntheses and molecular structures of [Sn{η-C5Me4(SiMe2But)}2] and [Fe{η-C5Me4(SiMe2But)}2]
Abstract
Reaction of 2 equiv. of LiCps[Cps= C5Me4(SiMe2But)] with MCl2(M = Sn or Fe) affords the metallocene compounds, [M(η-Cps)2], in high yield; single-crystal X-ray analyses of these metallocenes reveal the planar cyclopentadienyl rings to be parallel for both Sn and Fe derivatives.
