Notizen: Zum Verständnis der zentralen Rolle des Schwefels in Multi-Metall-Aggregaten mit verschiedener Elektronenpopulation: [S2WS2CoS2WS2]n- (n = 2, 3)/On the Central Role of Sulfur in Multi Metal Aggregates with Different Electron Populations: [S2WS2CoS2WS2]n-(n = 2, 3)

Abstract The hetero metal sulfur aggregates [Co(WS4)2] n- (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 WS42-(like MOS42-) is a non-innocent ligand and that the additional charge upon reduction is located mainly at the S atoms of the ligand system.
