Abstract Reaction of a new type of bidentate ligand PhPQu [PhPQu = 2‐diphenylphosphino‐4‐methylquinoline] with Fe(CO) 5 in butanol gave trans‐Fe(FpPQu‐P)(CO) 3 (1). Compound 1, which can act as a neutral tridentate organometallic ligand, was reacted with I B, II B metal compounds and a rhodium complex to give six binuclear complexes with FeM bonds, Fe(CO) 3 (μ‐Ph 2 PQu)MX n (2–7) [M= Zn(II), Cd(II), Hg(II), Cu(I), Ag(I), Rh(I)], and an ion‐pair complex [Fe(CO) 3 (μ‐Ph 2 PQu) 2 HgI][HgI 3 ] − (8). The structure of 8 was determined by X‐ray crystallography. Complex 8 crystallizes in the space group P ‐1 with a = 1.0758(3), b = 1.6210(4), c =1.7155(4)nm; a =75.60(2), β=71.81(2), γ=81.78(2)° and Z = 2 and its structure was refined to give agreement factors of R= 0.050 and R w = 0.057. The Fe‐Hg bond distance is 0.2536nm.
