Towards Larger Polygonal Architectures: Synthesis and Characterization of Iron(II)– and Ruthenium(II)–Bis(terpyridine) Metallomacrocycles

Five- through ten-membered homo- and heteronuclear metallomacrocycles possessing <tpy-FeII (or RuII)-tpy> connectivity have been prepared and isolated. Characterization includes a detailed analysis using traveling wave ion-mobility mass spectrometry, which allows the separation and identification of individual conformers based on size and charge. Conformer size derived from molecular modeling agrees well with collision cross-sections determined by the mass spectrometry experiments (see graphic).
