Di-iron aza diphosphido complexes: Mimics for the active site of Fe-only hydrogenase, and effects of changing the coordinating atoms of the bridging ligand in [Fe2μ-(ECH2)2NR(CO)6]
Abstract : The bis(phosphido)-bridged complex [Fe2(μ-PPhH) 2(CO)6] (1) undergoes double deprotonation to give the phosphorus-centered dianionic derivative [Fe2(μ-PPh) 2(CO)6]2- (2) which in turn reacts with the tertiary base RN(CH2Cl)2 to give [Fe 2(PPhCH2)2NR-(CO)6] (3) in moderate yield. Treatment of 3 with HBF4·Et2O affords the N-protonated species [Fe2(PPhCH2) 2NHR(CO)6] BF4 (4). The structural changes to the heavy atom skeleton of 3 arising from protonation are slight, the most obvious being a ca. 0.03 Å lengthening of the N-C bonds.
