A NOVEL REACTION BETWEEN μ-PhC(O)S-(μ-RS)Fe_2(CO)_6 AND (μ-R^1S)(μ-XMgS)Fe_2(CO)_6——THE SYNTHESIS, CHARACTERIZATION AND FORMATION MECHANISM OF TWIN CLUSTER COMPLEXES (μ-RS)Fe_2(CO)_6(μ_4-S)(μ-R^1S)Fe_2(CO)_6

摘要

The reaction of （μ-RS）（μ-XMgS）Fe2（CO）6 with PhC（O）Cl gave four new benzoyl complexes [μ-PhC（O）S]（μ-RS）Fe2（CO）6（R=Me, Et, n-Bu, CH2=CHCH2）, which further reacted with （μ-R1S）（μ-XMgS）Fe2（CO）6 to afford eight new twin cluster complexes with the general formula of [（μ-RS）Fe2（CO）6]（μ4-S）[（μ-R1S）Fe2（CO）6]. The single crystal X-ray analysis for one of these complexes （R=n-Bu, R1=Ph） showed that it consists of two different moieties PhSFe2（CO）6 and n-BuSFe2（CO）6 joined together through the spiran type of μ4-S., The complex belongs to space group P-1; cell parameters are a=9.028（3）, b=10.386（1）, c=16.723 （5）; α=87.70（2）°,β=75.67（2）°, r=82.26（2）°; z=2, Dx=1.743 g/cm3. Final deviation factor R=0.031.
