Enantiopure versus Racemic Mixture in Reversible, Two-Step, Single-Crystal-to-Single-Crystal Transformations of Copper(II) Complexes

Résumé

The reaction of chiral sodium complexes, 11[Na(SvalmetH)]·H2O (1-S) and 1 1[Na(R-valmetH)]·H2O (1-R), with copper(II) acetate affords chiral one-dimensional coordination polymers with the formulas 1 1[Cu(S-valmet)(H2O)]·H2O (2-S) and 1 1[Cu(R-valmet)(H2O)]·H2O (2-R) (R/S-valmetH2 are Schiff base proligands resulting from the condensation reactions between o-vanillin and R/S-methionine). The copper ions are connected by the carboxylato groups belonging to the amino-acid moieties, resulting in infinite chains showing syn-anti out-of-plane bridging mode.....
