Isolation of Elusive Fluoflavine Radicals in Two Differing Oxidation States.

ABSTRACT: Facile access and switchability between multiple oxidation states are key properties of many catalytic applications and spintronic devices yet poorly understood due to inherent complications arising from isolating a redox system in multiple oxidation states without drastic structural changes. Here, we present the first isolable, free fluoflavine (flv) radical flv(^1-•) as a bottleable potassium compound, [K(crypt-222)](flv^•), 1, and a new series of organometallic rare earth complexes [(Cp*₂Y)₂(μ-flv^z)]X, (where Cp* = pentamethylcyclopentadienyl, X = [Al(OC{CF₃}₃)₄]^- (z = -1), 2; X = 0 (z = -2), 3; [K(crypt-222)]⁺ (z = -3), 4) comprising the flv ligand in
