The title compound, [Fe(2)(C(14)H(10)NS(2))(2)(CO)(6)], was synthesized as a structural and biochemical model for the active site of [FeFe]-hydrogenase. The bond lengths (Fe-Fe, Fe-S and Fe-C) and angles (C-Fe-Fe and Fe-S-Fe) are within expected ranges. The S⋯S distance [2.9069 (12) Å] and the dihedral angle between two Fe-S-Fe planes [78.5 (3)°] of the butterfly-shaped Fe(2)S(2) core are enlarged compared with related bridged dithiol-ate diiron analogues. The calculated 4-benzothia-zolebenzyl best planes are almost parallel [dihedral angle = 3.7 (7)°].
标题化合物[Fe₂(C₁₄H₁₀NS₂)₂(CO)₆]被合成为[FeFe]-氢化酶活性位点的结构和生化模型。键长(Fe-Fe、Fe-S和Fe-C)和键角(C-Fe-Fe和Fe-S-Fe)在预期范围内。与相关的桥连二硫醇盐二铁类似物相比,蝶形Fe₂S₂核的S⋯S距离[2.9069 (12) Å]和两个Fe-S-Fe平面之间的二面角[78.5 (3)°]增大。计算得到的4-苯并噻唑苄基最佳平面几乎平行[二面角 = 3.7 (7)°]。
