(Figure Presented) Cores for thought: Structural and spectroscopic studies show that the {Cu2(S2)2}2+ core of [Cu2(tmeda)2(μ-S2)2]-(OTf) 2 (tmeda = N,N,N′,N′-tetramethylethylenediamine; OTf=trifluoromethane-sulfonate) is best described as a bis(μ-disulfido( .1-))dicopper(II) complex rather than a bis(μ-disulfido(2-))- dicopper(III) complex. This complex represents a new motif in the copper-sulfur chemistry of biologically relevant, synthetic model systems.
