摘　　要：A new thiolate-bridged diiron complex with two mono-coordinated azido ligands, [Cp＊Fe（kt-SMe）N3]2 （Cp^＊ = η^5-C5Me5）, was synthesized from [Cp＊Fe（η-SMe）MeCNMPF6]2 and NaN3 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）A, V = 9961.7（18） A3, C22H36Fe2N6S2, Mr = 560.39, Dc = 1.495 g/cm^3, F（000） = 4704,μ（MoKa） = 1.355 mm-I and Z = 16. The compound consists ofa di（u-thiolate）diiron unit {Cp＊Fe（p-SMe）}2, in which each iron is coordinated by a terminal azido ligand. Magnetic characterizations show spin canting behavior for the title compound.A new thiolate-bridged diiron complex with two mono-coordinated azido ligands, [Cp＊Fe（kt-SMe）N3]2 （Cp^＊ = η^5-C5Me5）, was synthesized from [Cp＊Fe（η-SMe）MeCNMPF6]2 and NaN3 in a bi-solvent system of acetone and methanol.
