Heteronuclear complexes containing the N,N′-di(2-pyridyl)amidocarboxylferrocene ligand

The ferrocene-derived ligand (NC5H4)2NOC–C5H4FeC5H5 reacts with arene ruthenium complexes [(η6-arene)RuCl2]2 to give the cationic complexes [(η6-p-iPrC6H4Me)RuCl{(NC5H4)2NOC–C5H4FeC5H5}]+ (1) and [(η6-C6Me6)RuCl{(NC5H4)2NOC–C5H4FeC5H5}]+ (2), isolated as the hexafluorophosphate and tetrafluoroborate salts, respectively, while the reaction with K2PtCl4 yields the neutral complex PtCl2{(NC5H4)2NOC–C5H4FeC5H5} (3). The molecular structures of 2 and 3 were confirmed by single-crystal X-ray diffraction.
