New guidelines for the design of structurally equivalent molecular crystals were derived from structural analyses 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 exchanged atom is not involved in hydrogen bonding.
