A coordinatively unsaturated dinuclear Fe(II) complex of bulky thiolates, [(TipS)Fe(¦Ì-SDmp)]2 (1; Tip = 2,4,6-iPr3C6H2, Dmp = 2,6-(mesityl)2C6H3), was synthesized from stepwise reactions of Fe{N(SiMe3)2}2 with 1 equiv of HSDmp and then with 1 equiv of HSTip. Complex 1 was found to react with elemental S (S8) in toluene to generate a new class of [8Fe-7S] cluster, [(DmpS)Fe4S3]2(¦Ì-SDmp)2(¦Ì-STip)(¦Ì6-S) (2). The cluster 2 was also produced from 1-pot reactions of Fe{N(SiMe3)2}2 + HSDmp + HSTip + S8 (8p6:10:7/8) and Fe3{N(SiMe3)2}2(¦Ì-STip)4 + HSDmp + S8 (8/3:16/3:7/8), where another [8Fe-7S] cluster, [(TipS)Fe4S3]2(¦Ì-SDmp)2{¦Ì-N(SiMe3)2}(¦Ì6-S) (3), was also found as a minor byproduct. In either of the clusters, two Fe4S3 incomplete cubane units are connected by three anionic ligands, three thiolate S atoms for 2 or two thiolate S atoms and one amide N atom for 3, and one hexacoordinate S atom resides at the center of the [8Fe-7S] core. They have a common Fe(II)5Fe(III)3 oxidation states, and an S = 1/2 ground spin state was indicated by rhombic EPR signals at 10 K with g = 2.19, 2.07, and 1.96 for 2 and g = 2.13, 2.06, and 1.93 for 3. The structural relevance of clusters 2 and 3 to P-cluster, FeMo-co, and FeFe-co of nitrogenases is discussed.
