Binuclear complexes containing an iron(I)-mercury(I) bond from oxidation of trans-[Fe(CO) 2(CS 2)(Ph 2Ppy- P) 2] with HgX 2 (Ph 2Ppy = 2-(diphenylphosphino) pyridine, X = Cl, SCN)

Abstract

trans-[Fe(CO) 2(CS 2)(Ph 2Ppy- P) 2] reacts with HgX 2 (X = Cl, SCN) in dichloromethane at room temperature to give heterodinuclear complexes XFe(CO) 2(μ-Ph 2Ppy) 2HgX (X = SCN, 1; X = Cl, 2) containing an iron(I)-mercury(I) bond. The Fe(I)-Hg(I) bond length as determined by X-ray analysis is 2.527(2) Å for 1 and 2.529(1) Å for 2.
