Abstract

An unusual iridium complex, [(dfpbo)(2)Ir](2) [dfpbo = 2-(3,5-difluorophenyl)benzoxazolato-N,C(2')], which is the first dimeric iridium complex composed of two bis-cyclometalated Ir(II) structures connected by an unsupported Ir(II)-Ir(II) bond, has been synthesized and fully characterized. Under mild conditions of neutral pH at room temperature, this complex dissociated spontaneously to form the stable radical [Ir(dfpbo)(2)]*.
