Abstract

Recently the crystal structure of [Co(acac) (R-dqpn')] C1O4 was described4 as comprising equal amounts of Δ-β and Δ-β cations with positional disorder of the pn methyl group. Another isomerism was present in that the nitrogen α or β to the asymmetric carbon could be deprotonated. Nevertheless, only two doublets due to these methyl groups were observed in the 1H NMR spectrum of the complex and its conjugate acid, and this was interpreted as arising from a facile rearrangement of the diastereomer population in solution.
