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

The ferrocene-derived ligand (NC5H4)2NOC-C5H4FeC5H5 reacts with arene ruthenium complexes [(?6-arene)RuCl2]2 to give the cationic complexes [(?6-p-iPrC6H4Me)RuCl{(NC5H4)2NOC-C5H4FeC5H5}]+ (1) and [(?6-C6Me6)RuCl{(NC5H4)2NOC-C5H4FeC5H5}]+ (2), isolated as the hexafluorophosphate and tetrafluoroborate salts, resp., while the reaction with K2PtCl4 yields the neutral complex PtCl2{(NC5H4)2NOC-C5H4FeC5H5} (3). The mol. structures of 2 and 3 were confirmed by single-crystal x-ray diffraction. [on SciFinder(R)]
