Abstract

In the title compound, [Fe(2)(C(4)H(2)N(2)S(2))(C(3)H(9)P)(CO)(5)], the Fe(2)S(2) core adopts a butterfly conformation. The PMe(3) ligand is coordinated in the basal position, roughly cis to the Fe-Fe bond. The Fe-Fe distance of 2.4970 (6) Å is relatively short compared to those (ca 2.53 Å) found in another monosubstituted diiron compound. A rigid planar dithiol-ate bridge is featured, with an angle of 2.78 (1)° between the Fe-Fe bond and the normal to the pyrazine-2,3-dithiol-ate plane.
