Two new iron-sulfur carbonyl complexes, [Fe2(SC6H4Cl)2(CO)6]?0.5(Et2O) 1 and [Fe3(SC6H4NH2)6(CO)6]?2(MeOH) 2, have been prepared and characterized by elemental analysis, IR spectra and single-crystal X-ray diffraction. Crystal data for 1: monoclinic, C2/c, a = 18.4439(8), b = 11.0999(5), c = 25.1830(10) ?, β = 97.0370(10)o, V = 5116.8(4) ?3, Z = 8, C20H13Cl2Fe2O6.50S2, Mr = 604.02, Dc = 1.568 g/cm3, μ = 1.540 mm–1, F(000) = 2424, the final R = 0.0545 and wR = 0.1454 for 3443 observed reflections with I > 2σ(I); 2: monoclinic, P21/n, a = 12.350, b = 26.3050(11), c = 16.057 ?, β = 97.891(3)°, V = 5166.9(2) ?3, Z = 4, C44H44Fe3N6O8S6, Mr = 1144.76, Dc = 1.472 g/cm3, μ = 1.128 mm–1, F(000) = 2352, the final R = 0.0442 and wR = 0.1197 for 7978 observed reflections with I > 2σ(I). Complex 1 contains one iron dimer, in which two tricarbonyliron(I) fragments are bridged together by two 4-chlorophenylthiolate ligands, whereas complex 2 contains a linear tri-iron cluster, in which two terminal tricarbonyliron(II) fragments and the central Fe(II) atom are linked together by six 4-aminophenylthiolate bridging ligands.
