Popis:	Diiron dithiolate complexes have received special attention because of their structural similarity to the active site of [FeFe]-hydrogenases, which are the most efficient and fastest catalysts for the generation of dihydrogen in nature. Recently, we established a novel and efficient way to prepare phosphine-substituted diiron aza- and oxadithiolate complexes. Reaction of Fe2(μ-SCH2OH)2(CO)6 and several phosphine ligands L (L = PPh3, PPh2(2-C5H4N), P(C6H4-4-CH3)3) affords the intermediate Fe2(μ-SCH2OH)2(CO)5L, while the intermediate in situ reacts with primary amines RNH2 (R = CH2CH2CH(CH3)2, CH2CH2CH2SCH3, C6H4-4-CH3) to produce the target phosphine-substituted diiron azadithiolate complexes Fe2[(μ-SCH2)2NCH2CH2CH(CH3)2](CO)5(PPh3) (1), Fe2[(μ-SCH2)2NCH2CH2CH(CH3)2](CO)5[PPh2(2-C5H4N)] (2), Fe2[(μ-SCH2)2NCH2CH2CH(CH3)2](CO)5[P(C6H4-4-CH3)3] (3), Fe2[(μ-SCH2)2NCH2CH2CH2SCH3](CO)5(PPh3) (4), Fe2[(μ-SCH2)2NCH2CH2CH2SCH3](CO)5[PPh2(2-C5H4N)] (5), Fe2[(μ-SCH2)2NCH2CH2CH2SCH3](CO)5[P(C6H4-4-CH3)3] (6), Fe2[(μ-S...
