π-Complexed polyfluoroarenes: a reactivity, bonding and spectroscopic study of (η6-C6F6)Cr(η6-C6H6) and related molecules

Organometallic Complexes of Graphene: Toward Atomic Spintronics Using a Graphene Web

“…We explained these phenomena on the basis of spinÀcharge separation, a fundamental property of the systems with πÀd interactions. Moreover, we propose an efficient and experimentally feasible 49 approach to control the electronic properties of these systems by using the arene ligand as a local gate. Thus, by varying the number of substituents in the G|Cr|(C 6 H 6Àx F x ) system it was possible to achieve either an open-gap state or a zero-gap material with linear dispersion at the Fermi level provided by the interplay of π* graphene and localized 3d metallic states.…”

From ferrocene to 1,2,3,4,5-pentafluoroferrocene: halogen effect on the properties of metallocene

“…[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).…”
