Organoamidometallics—IV. Syntheses of N,N′-bis(polyfluorophenyl)ethane-1,2-diaminato(2−)platinum(II) complexes with two different fluorocarbon groups

Syntheses and structures of N-polyfluorophenyl- and N,N′-bis(polyfluorophenyl)ethane-1,2-diaminato(1- or 2-)platinum(II) complexes

“…Although the former should show two CH 2 resonances and two different pyridine ligands, previous 1 H NMR spectra of analogous complexes with two different polyfluoroaryl groups usually gave a single CH 2 and one set of py resonances [23]. (Separation of CH 2 resonances and two sets of pyridine resonances was observed only when one polyfluorophenyl group was replaced by an unsubstituted phenyl [25].)…”
