| Abstract: | ![]()
Three diiron carbonyl complexes, namely [(η 5-C5H4)(η 3-C(CH2)2)]Fe2(CO)5 (1), [(C2H5)2C(η 5-C5H4)2]Fe2(μ-CO)2(CO)2 (2), and [(CH2)4C(η 5-C5H4)(η 5-C5H3)(C5H9)]Fe2(μ-CO)2(CO)2 (3), have been synthesized by the reactions of C5H4C(Me)2, C5H4C(Et)2, and C5H4C(CH2)4, respectively, with Fe(CO)5 in refluxing xylene. The complexes have been characterized by elemental analysis, IR, and 1H NMR spectra. The molecular structures of the complexes have been determined by single-crystal X-ray diffraction. The structures of the complexes indicate that fulvenes can be bound to transition metal centers by diverse modes. |
