N2 - The review provides insight into the mechanism of ligand substitution and electron transfer (from chromium(
III) to iron(III)) by comparison of the reactivity of some tetraazamacrocyclic chromium(III) complexes
in the conjugate acid-base forms. Use of two geometrical isomers made possible to estimate
the influence of geometry and protolytic reactions in trans and cis position towards the leaving group
on the rate enhancement. Studies on the reaction rates in different media demonstrated the role played
by outer sphere interactions in a monodentate ligand substitution.
