The tetradentate ligands N,N'-dialkyl-2,11-diaza3,3pyridinophane (N4, where R = Me or tBu) were employed to synthesize and fully characterize [(N4)M(COD)] complexes (M = Rh or Ir; COD = cyclooctadiene). Interestingly, these complexes exhibit accessible oxidation potentials and can generate detectable [(N4)M(COD)] complexes, which were characterized by electron paramagnetic resonance and high-resolution electrospray ionization mass spectrometry. Moreover, a rare mononuclear [(N4)Rh(COD)] complex was isolated and crystallographically characterized, allowing for a direct comparison with its rhodium(I) analogue. The detailed characterization of such paramagnetic rhodium(II) and iridium(II) complexes enables further investigation of their redox reactivity.
采用四齿配体N,N'-二烷基-2,11-二氮杂3,3吡啶并环（N4，其中R = 甲基或叔丁基）合成并全面表征了[(N4)M(COD)]配合物（M = 铑或铱；COD = 环辛二烯）。有趣的是，这些配合物具有可及的氧化电位，并且能够生成可检测的[(N4)M(COD)]配合物，通过电子顺磁共振和高分辨率电喷雾电离质谱对其进行了表征。此外，分离出一种罕见的单核[(N4)Rh(COD)]配合物并通过晶体学进行了表征，从而能够与其铑(I)类似物进行直接比较。对此类顺磁性铑(II)和铱(II)配合物的详细表征使得能够进一步研究它们的氧化还原反应活性。
