Synthesis and X-ray structural characterization of [Me4N]3{[(SCH2CH2S)MoS3]2Fe}, the first example of a heteronuclear trimer containing molybdenum in a square-pyramidal geometry

Abstract

Reaction of a mixture of (NH₄)₂MoS₄ disodium ethane-1,2-dithiolate in dimethylformamide-MeCN with a methanolic solution of anhydrous FeCl₃, followed by the addition of Me₄NBr, gives the trinuclear complex [Me₄N]₃{[(SCH₂CH₂S)MoS₃]₂Fe}, an X-ray crystal structure of which shows the molybdenum atoms to have distorted square-pyramidal geometry and the iron atom to be tetrahedrally co-ordinated to four µ-sulphido-ligands.
