R(-)-2-methyl-1,4,7- triazacyclononane and its cobalt(III) complex [Co (R-MeTACN)2]3+ is reported. The complex is found to exhibit in the 480 nm region the largest ring-conformation d-electron opticalactivity yet recorded for the [CoN6 chromophore, due to a chiral puckering, with the λ-conformation, of each of the six chelate rings. The c.d. spectrum of the complex is found to be consistent with the dynamic
