Abstract: New guidelines for the design of structurally equivalent molecular crystals were derived from a structural analysis of new cocrystals and polymorphs of saccharin and thiosaccharin, aided by a computational study. The study shows that isostructural crystals may be obtained through an exchange of >C=O with >C=S in the molecular components of the solids, but only if the ex-changed atom is not involved in hydrogen bonding.
