| Beschreibung: | Intermolecular interactions play an important role in the formation and stability of co-crystals. In this study, the interaction behaviour of theophylline in co-crystal structures was systematically analysed using data from the Cambridge Structural Database. A total of fifty-three theophylline co-crystal structures were investigated and classified according to their intermolecular interaction motifs. A structured interaction scheme was developed to describe the accessible interaction sites of theophylline, including classical and non-classical hydrogen bonds, as well as halogen bonds and π∙∙∙π interactions. The study revealed theophylline’s high versatility in forming intermolecular interactions, resulting in twenty interaction patterns. Three dominant motifs were identified as occurring most frequently. The results indicate that steric effects influence the accessibility of specific interaction sites, particularly limiting interactions at the carbonyl group located between the two methyl groups. Hirshfeld surface analysis revealed that O∙∙∙H and H∙∙∙H interactions contribute most significantly to the intermolecular interactions in the analysed structures. | |||||||
