Exploring two distinct crystallization pathways of pyridinoyl-hydrazone derivatives of isosteviol: true and pseudosymmetric homochiral motifs
摘要
The coexistence of two fragments, a chiral isosteviol moiety and an achiral pyridinoyl-hydrazone moiety, in the molecules of pyridinoyl-hydrazone derivatives of isosteviol results in the realization of two distinct supramolecular motifs in their crystals, namely, a true homochiral motif and a pseudosymmetric homochiral motif.
