AbstractThe coordination chemistry of the ferrocene ligands [(4-pyridylamino) carbonyl]ferrocene (L1) and 1,1′-bis[(4-pyridylamino)carbonyl]ferrocene (L2) with group 11 metals and thallium has been studied, and several complexes with coordination of the metal to the pyridine nitrogen atom or to the pyridine and carbonyl group have been prepared. For the ligand L1 complexes such as [AuX(L1)] (X = Cl, C 6F 5), [M(PPh 3)(L1)]OTf (M = Au, Ag) (OTf = trifluoromethylsulfonate), [Ag(OTf)(L1)] or [M(L1) 2] + (M = Au, Ag, Cu) have been obtained. The thallium compound [Tl 2(L1) 4] 2+ has also been prepared by reaction of Tl(PF 6) with L1 and show an interesting structural framework with formation of a metalacycle resembling a macrocyclic compound. For the disubstituted ligand L2 dinuclear complexes such as [Au 2(C 6F 5) 2(μ-L2)] or [M 2(PPh 3) 2(μ-L2)](OTf) 2 (M = Au, Ag) or the polymeric species [Ag(μ-L2)]OTf have been isolated. The crystal structures of some of these derivatives show supramolecular assemblies through hydrogen bonding. © 2012 Elsevier B.V. All rights reserved.
