Abstract:A new thiolate-bridged diiron complex with two mono-coordinated azido ligands, [Cp*Fe(mu-SMe)N-3](2) (CP* =eta(5)-C5Me5), was synthesized from [Cp*Fe(mu-SMe)MeCN](2)[PF6](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) angstrom, V = 9961.7(18) angstrom 3, C22H36Fe2N6S2, M-r = 560.39, D-c = 1.495 g/cm(3), F(000) = 4704, mu(MoK alpha) = 1.355 mm(-1) and Z = 16. The compound consists of a di(mu-thiolate)diiron unit {Cp*Fe(mu-SMe)}(2), in which each iron is coordinated by a terminal azido ligand. Magnetic characterizations show spin canting behavior for the title compound.
