Abstract
Variable temperature 13C NMR studies of the pendant arm macrocyclic complex N,N′,N″,N‴-tetrakis(2-hydroxyethyl)-1,4,7,10-tetraazacyclododecanelead(II) and its cadmium(II) and mercury(II) analogues in [2H4]-methanol indicate that these complexes undergo rapid intramolecular exchange between two square antiprismatic enantiomers.Keywords
