The series of diiron oxadithiolate model complexes for the active site of [Fe]-only hydrogenases Fe 2 (μ-SCH 2 OCH 2 S-μ)(CO) 6 ( 1 ), [Fe 2 (μ-SCH 2 OCH 2 S-μ)(CN) 2 (CO) 4 ](Et 4 N) 2 ( 2 ), [Fe 2 (μ-SCH 2 OCH 2 S-μ)(CN)(CO) 5 ](Et 4 N) ( 3 ), Fe 2 (μ-SCH 2 OCH 2 S-μ)(CO) 5 [CpFe(CO) 2 (SPh)] ( 4 ), and [Fe 2 (μ-SCH 2 OCH 2 S-μ) (CO) 5 ] 2 [(η 5 -Ph 2 PC 5 H 4 ) 2 Fe] ( 5 ) have been synthesized and fully characterized by elemental analysis, spectroscopy, and X-ray diffraction analysis. The structural features for some of the model complexes are compared with the corresponding features for the active site of [Fe]-only hydrogenases.
