Synthesis of tri- and tetranuclear metal-sulfur clusters by the reaction of a trisulfido-bridged diiron complex with W(CO)(5)THF
Reaction of trisulfido-bridged diiron complex [CpFe(CO)(2)](2)(mu -S-3) with 0.8 equiv of W(CO)(5)THF produced a trinuclear cluster [CpFe(CO)(2)](2)(mu (3)-S-3)W(CO)(5) in which the W(CO)(5) moiety was selectively coordinated to one of the alpha -sulfur atoms of the trisulfido ligand. The reaction with an excess of W(CO)(5)THF afforded a tetranuclear cluster [CpFe(CO)(2)](2)(mu (4)-S-3)[W(CO)(5)](2) as a major product in which the W(CO)(5) moieties were coordinated to both of the alpha -sulfur atoms of the trisulfido ligand.
