چکیده
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.

The title compound, [Fe(2)(C(9)H(11)NS(2)){Fe(C(5)H(5))(C(17)H(14)P)}(CO)(5)], was prepared as an aza-dithiol-ato-iron model for the iron-only hydrogenase active site. The Fe(2)S(2) unit exhibits a butterfly conformation and the ferrocenyldiphenyl-phosphine ligand is trans to the Fe-Fe bond. The Fe-Fe distance of 2.5160 (8) Å is longer than found in related model structures. Intra-molecular C-H...
