(H)Cl] and [Ir(PPh(3))(2)(NO-R)(H)(2)] complexes, the 2-(arylazo)phenolate ligands are coordinated to the metal center as monoanionic bidentate N,O-donors, whereas in the [Ir(PPh(3))(2)(CNO-R)(H)] complexes, they are coordinated to iridium as dianionic tridentate C,N,O-donors. In all three products formed in ethanol, the two PPh(3) ligands are trans. Reaction of 2-(arylazo)phenols with [Ir(PPh(3))(3)Cl]
2-(芳基偶氮)酚与[Ir(PPh(3))(3)Cl]在回流乙醇中,在碱(NEt(3))存在下反应,得到三种不同类型的配合物,即。[Ir(PPh(3))(2)(NO-R)(H)Cl](R = OCH(3),CH(3),H,Cl和NO(2)),[Ir(PPh(3) ))(2)(NO-R)(H)(2)]和[Ir(PPh(3))(2)(CNO-R)(H)]。[Ir(PPh(3))(2)(NO-Cl)(H)Cl],[Ir(PPh(3))(2)(NO-Cl)(H)(2)]和[ Ir(PPh(3))(2)(CNO-Cl)(H)]络合物已通过X射线晶体学测定。在[Ir(PPh(3))(2)(NO-R)(H)Cl]和[Ir(PPh(3))(2)(NO-R)(H)(2)]络合物中, 2-(芳基偶氮)酚盐配体以单阴离子二齿N,O-给体的形式配位到金属中心,而在[Ir(PPh(3))(2)(CNO-R)(H)]
