摘要：
We describe the synthesis and reactivity towards metal cations of metalloligands that contain a Fe-Hg-Fe chain-like core consisting of two iron carbonyl fragments bonded to a central mercury atom and linked to a donor function available for further metal complexation. Free rotation of these fragments about the Fe-Hg-Fe metal-metal sigma bonds allows greater adaptability to the nature and stoichiometry of the added metal complex. The structures of the chain complexes [Hg{Fe[Si(OMe)(3)](CO)(3)(dppm-E)}(2)](6, E = S; 7, E =0) with pendent phosphine sulphide or oxide moieties were determined by single crystal X-ray diffraction.
