Synthesis and Characterization of a Thiolate-bridged Diiron Complex with Two Monocoordinated Azido Ligands: [Cp^*Fe（μ-SMe）N₃]₂ （Cp^* = η⁵-C₅Me₅）

【摘要】 A new thiolate-bridged diiron complex with two mono-coordinated azido ligands, [Cp*Fe(μ-SMe)N3]2 (Cp* =η5-C5Me5 ), was synthesized from [Cp*Fe(μ-SMe)MeCN]2[PF6] 2 and NaN 3 in a bi-solvent system of acetone and methanol. X-ray crystal structural analysis shows that the compound belongs to the orthorhombic Fdd2 space group, with a = 14.3771(15), b = 71.424(8), c = 9.7010(10) , V = 9961.7(18) 3 , C22H36Fe2N6S2 , Mr = 560.39, Dc = 1.495 g/cm 3 , F(000) = 4704, μ(MoKα) = 1.355 mm-1 and Z = 16. The compound consists of a di(μ-thiolate)diiron unit {Cp*Fe(μ-SMe)} 2 , in which each iron is coordinated by a terminal azido ligand. Magnetic characterizations show spin canting behavior for the title compound.更多还原
