Abstract
The synthesis of the new ligand, (C5Me 4 Bu)H was described and its reaction with Fe(CO)5 to prepare (C5Me 4 Bu)2Fe2(CO)4 was presented. The structure of complex was characterized by IR, 1H NMR, elemental analysis and single crystal X-ray diffraction. It confirms the complex is a dimer with bridging and terminal CO groups. The Fe–Fe bond distance is 2.5508(9) A. (C5Me 4 Bu)2Fe2(CO)4 belongs to triclinic: space group P ī, with a = 8.5468(17) A, b = 8.8997(18) A, c = 9.4044(19) A, α = 89.52(3)°, β = 74.11(3)°, γ = 86.42(3)°, V = 686.6(2) A3, Z = 2, Dc = 1.399 g cm−3, μ (MoKα) = 1.090 mm−1, F(000) = 306, and final R 1 = 0.0324, wR 2 = 0.0852 for observed reflections 2,396 (I > 2σ(I)). The synthesis of the new ligand, (C5Me 4 Bu)H was described and its reaction with Fe(CO)5 to prepare (C5Me 4 Bu)2Fe2(CO)4 was presented. Single crystal X-ray diffraction analysis reveals that the molecular structure of this complex is a dimmer.
