Abstract: | Synthesis of the novel ligand ferrocenyliminophosphine [(η5-C5H5)Fe{(η5-C5H4)CHN(C6H4-2-PPh2)}] (1, L) and studies on its complexation properties with mercury (II) are reported. Halogen-bridged binuclear mercury (II) complexes [HgX(μ-X)L]2 (X = Cl (2a), Br (2b)) and a mononuclear mercury (II) complex HgCl2L2 (4a) have been obtained under different reaction conditions. In both cases, the ferrocenyliminophosphine acts as a P-monodentate ligand and the imino nitrogen does not participate in coordination to mercury (II). All the new compounds 1, 2a, 2b and 4a were characterized by elemental analysis, 1H NMR, 31P NMR and IR spectra. In addition, structures of 2a and 4a have been determined by X-ray single-crystal analysis. |
