title: First isolation of fully delocalized mixed-valent imido-bridged [Ti2]7+ complexes by one-electron reduction of [(C5R5)TiCl]2(μ-NAr)2.
abstract: Mixed-valent imido-bridged dinuclear titanium complexes, [Cp(2)Co][{(C(5)R(5))TiCl}(2)(μ-NAr)(2)] (R = H, Me; Ar = 3,5-(CF(3))(2)C(6)H(3)), were prepared by one-electron reduction of the corresponding [(C(5)R(5))TiCl](2)(μ-NAr)(2). One unpaired electron is delocalized in the central Ti(μ-NR)(2)Ti core as the first example of a fully delocalized mixed-valent imido-bridged [Ti(2)](7+) species.
