尽管其作为过渡金属的氧原子转移试剂的实用性，但一氧化二氮（N2 O）是众所周知的差配体，并且其配位化学仅限于少数末端、末端上的κ（1）-N络合物。在这里，单核钴配合物具有侧上绑定N2 O分子的合成报告。结构表征，红外光谱，和DFT计算支持的eta（2）-N，N结合模式的N2 O的钴中心的结合。
Despite its utility as an oxygen-atom transfer reagent for transition metals, nitrous oxide (N2O) is a notoriously poor ligand, and its coordination chemistry has been limited to a few terminal, end-on kappa(1)-N complexes. Here, the synthesis of a mononuclear cobalt complex possessing a side-on-bound N2O molecule is reported. Structural characterization, IR spectroscopy, and DFT calculations support an eta(2) -N,N binding mode for binding of N2O to the cobalt center.
