Side-On Coordination of Nitrous Oxide to a Mononuclear Cobalt Center

J Am Chem Soc. 2019 Sep 25;141(38):15003-15007. doi: 10.1021/jacs.9b08241. Epub 2019 Sep 11.


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 κ1-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 η2-N,N binding mode for binding of N2O to the cobalt center.
