説明
<jats:title>Abstract</jats:title> <jats:p>A reaction of [{Cp*IrCl(μ-Cl)}2] (Cp* = η5-C5(CH3)5) with 1-(pyridin-2-yl)ethanone oxime (PyNOH) afforded the cationic oxime complex [Cp*IrCl(PyNOH)]Cl (3) with an acidic OH group at the β-position to the metal center. Complex 3 underwent reversible deprotonation to give the corresponding oximato complex [Cp*IrCl(PyNO)] (4), while treatment of 3 with silver triflate in acetonitrile led to the formation of the dicationic complex [Cp*Ir(PyNOH)(CH3CN)][OTf]2 (5, OTf = OSO2CF3). The detailed structures of 3–5 have been determined by X-ray crystallography.</jats:p>
