“…[16][17][18] Despite these interests and the role of metallocenes in many of these areas of fundamental and applied interest, few polyfluorometallocenes have been described, and structureproperty relationships are limited in scope. [19][20][21] Concerning η 6 coordination compounds, a few arene-vanadium, 22 chromium [23][24][25][26][27][28] and -rhodium 29,30 complexes with up to six fluorine atoms on the aromatic ring have been reported. However, η 5 -coordination complexes are limited to a handful of examples (Figure 1).…”
