abstract = {The homochiral iron(III) wheels [Fe(6){(S)-pedea}(6)Cl(6)]
and [Fe(6){(R)-pedea)}(6)Cl(6)] [(R)- and (S)-2; pedea =
phenylethylaminodiethoxide] exhibit high optical activities
and antiferromagnetic exchange. These homochiral products
react with each other, producing the centrosymmetric,
crystallographically characterized
[Fe(6){(S)-pedea}(3){(R)-pedea}(3)Cl(6)] diastereomer
[(RSRSRS)-2]. (1)H NMR and UV-vis studies indicate that
exchange processes are slow in both homo- and heterochiral
systems but that, upon combination, the reaction between
(R)- and (S)-2 occurs quickly.},
