Abstract
Racemic and resolved [CrIII(C2O4)3]K3 dissolved in water were investigated by IR spectroscopy. Compared to the racemic compound, the spectrum of the resolved one exhibits additional peaks, which have a complex temporal evolution. These peaks are attributed to water molecules coordinated to the metal ion and tentatively related to the formation of a pure chiral solid phase of two-dimensional (2D) oxalate-based Mn–Cr networks starting from partially resolved [CrIII(C2O4)3]3–.
