Abstract

Oxidation of [Fe(CO)2(′N2H2S2′')] (1) (′N2H2S2'2- = 1,2-ethanediamine-N,N′-bis(2-benzenethiolate)(2—)) gave insoluble [Fe(′N2S2')]2 (2) ('N2S2'2- = glyoxal-bis(2-mercaptoanil)(2—)). Dinuclear, thiolato-bridged 2 was characterized by single crystal X-ray structure analysis. It does not react with CO or H2, but yields bis or mono adducts with PR3 (R = Me, n-Bu, Cy).
