Union is strength: π-π stacking interactions are capable of preventing solid-state racemization of tris-chelate complexes

The first reliable observation of desolvation- and temperature-induced solid-phase racemization of the entire tris-chelates complex is reported. The capability of π-π stacking interactions to prevent such processes was revealed for the first time. The first reliable observation of the solid-phase racemization of the entire tris-chelate complex is reported. The decisive effect of the π-π stacking on this process is revealed.
