1 Source of material

A mixture of [Fe2(CO)6(μ–SeC6H5)2] (118 mg, 0.2 mmol) and (Ph2P)2NC6H4-3–CCH (97 mg, 0.2 mmol) was dissolved in 15 mL of xylene. The reaction mixture was stirred at reflux for 1 h. After removing the solvent under vacuum, the residue was subjected to preparative TLC separation using dichloromethane/pentane (1:1, v/v) as eluent. The title complex was obtained as a deep-red solid (yield 38 %) from the main band. Single crystals were obtained by diffusing the dichloromethane solution into a hexane solution at room temperature.

2 Experimental details

The structure was solved by Direct Methods with the SHELXS program. Hydrogen atoms were positioned geometrically (C–H = 0.93–0.98 Å). Their Uiso values were set to 1.2 Ueq or 1.5 Ueq of the parent atoms.

3 Comment

Hydrogenase is considered a highly promising catalyst capable of catalyzing hydrogen production under mild conditions. 5 In recent years, hydrogenase model compounds containing the 2Fe2Se unit have garnered considerable attention as synthetic catalysts. The unique structure and activity of these model compounds make them powerful tools for understanding the catalytic mechanisms of natural hydrogenase and for designing novel catalysts. 6 , 7 They share similarities in structure with the active center of natural hydrogenase but offer greater flexibility in synthesis and regulation. A series of mono- and di-phosphine substituted Fe/Se model compounds have been reported. 8 – 12 Herein, we carried out the CO substitution reaction of [Fe2(CO)6(μ–SeC6H5)2] with a disphosphine ligand (Ph2P)2NC6H4-3–CCH, and obtained the title complex. The title complex comprises a 2Fe2Se cluster with four carbonyls and one diphosphine ligand. The Se1 and Se2 atoms are linked to the two phenyl substituents through axial Se1–C37 and Se2–C43 equatorial bonds. The two phosphorus atoms of diphosphine ligand are positioned at the cisoid dibasal site, symmetrically connecting the two Fe atoms, resembling the previously reported analogues. 13 , 14 The bond length Fe1–Fe2 [2.4916(14) Å] is slightly longer than that of sulfur analogues, and the average Se–Fe–Se angles in the title complex are more open than those in sulfur analogues. 15 – 19
