The intramolecular rearrangement of 2-(5-cyanotetrazolato)pentaammine cobalt (III) perchlorate (CP) to form the amidine chelate perchlorate coordination complex has been investigated by variable-temperature high-resolution proton nuclear magnetic resonance (NMR) spectroscopy. Using a concentration of 30 wt % CP in perdeuterodimethylsulfoxide ((CD/sub 3/)/sub 2/SO), the rate of formation of the amidine chelate was determined at five different temperatures (60, 70, 80, 90, and 100/sup 0/C). The logarithm of the specific rate constant at each temperature was plotted as a function of the reciprocal absolute temperature to arrive at the activation energy, E/sub a/ (19.5 kcal/mole), for the rearrangement process. 4 refs., 4 figs., 1 tab.
