Iron complexes triple-stranded helicates

Zclikovich, L., Libman, J., and Shanzer, A. Molecular redox switching based on chemical triggering of iron translocation in triple-stranded helical complexes. Nature 199.5, 374, 790-792. 

This is illustrated by the heterochiral triply helical dinuclear Fe(II) complex (5.16). Thus when the bis(bipyridine) ligand 14 with a methylene spacer was treated with the iron(II) complex, only one isomer was obtained and identified as a binuclear heterochiral triple-stranded helicate [Fe2(14)3]" (5.16) (Scheme 5.7). Interestingly the H-NMR...
