Description:
<jats:title>Abstract</jats:title>
<jats:p> The hetero metal sulfur aggregates [Co(WS<jats:sub>4</jats:sub>)<jats:sub>2</jats:sub>] <jats:sup>n-</jats:sup> (with variable electron population: n = 2, 3) could be isolated as salts and characterized by physical measurements (in-cluding X-ray structure analysis). Experimental and theoretical investigations show that due to a strong metal → ligand electron delocalisation WS4<jats:sup>2-</jats:sup>(like MOS<jats:sub>4</jats:sub>
<jats:sup>2-</jats:sup>) is a non-innocent ligand and that the additional charge upon reduction is located mainly at the S atoms of the ligand system.</jats:p>
