Coordination chemistry of organometallic polydentate ligands. Syntheses of Fe-M complexes using Fe(CO)4(Ph2Ppy-P)[Ph2Ppy = 2-(Diphenylphosphino)pyridine] and Trans-Fe(PhPMepy)2(CO)3[PhPMepy = 2-(Phenylmethylphosphino)pyridine] as a neutral Bi-or tridentate ligand

Fe(CO)₄(Ph₂Ppy-P) (1), prepared by the oxygen-atom transfer reaction, reacted as an organometallic bidentate ligand with HgX₂ (X = Cl, I) to form binuclear complexes containing a Fe - Hg bond and treatment of the organometallic tridentate ligand trans-Fe(PhPMepy)₂(CO)₃ (2) with M(CO)₆ (M = Cr, Mo), M(SCN)₂ (M = Zn, Cd, Co, Ni, Mo), HgX₂ (X = Cl, I) and CdCl₂ also afforded binuclear complexes including a Fe - M bond. The crystal and molecular structures of the Fe-Hg complexes (CO)₄Fe(μ-Ph₂Ppy)Hg(μ-Cl)²HgCl ₂ (3), (CO)₃Fe(μ-PhPMepy)₂Hg(μ-Cl)₂HgCl ₂·1/2CH₂Cl₂ (5) and (CO)₃Fe(μ-PhPMepy)₂Hg(μ-I)₂HgI ₂·3CH₂Cl₂ (6) have been determined.
