complex bis(RR-2,5,8-triazabicyclo[7.4.01,9]tridecane)cobalt(III) chloride hexafluorophosphate the cyclohexane rings and pairs of adjacent secondary amines occupy an approximate plane around the cobalt ion, with the remaining secondary amines in each tridentate ligand in trans dispositions. A large positive Cotton effect occurs under the low energy absorption band in the circular dichroism spectrum of this
