Research output: Contribution to journalArticlepeer-review


The crystal and molecular structures of the stable nitroxide radical 2,4,4,5,5-pentamethyl-2-imidazoline-1-oxyl-3-oxide was determined. The N-O bond lengths are 1.279(2) and 1.280(2) Å, respectively. The O --N+=C-N-•O fragment is nearly planar with carbon atoms of the ethyl fragment that deviated from the O-N+=C-N-•O plane by -0.204(5) and +0.176(5) Å. The minimum intermolecular distance between the oxygen atoms of NO groups is 4.094 Å.
