Abstract
Halogen Bonding (XB) is a noncovalent interaction with net attractive interaction between the electrophilic region, an area with the tendency to attract electrons, and the nucleophilic region, an area with the tendency to donate electrons. Cocrystals are formed when XB acceptors and donors come together; these can then be analyzed through single-crystal X-ray diffraction. This research focused on using nitrogen and iodine compounds due to their uneven distribution of electrons, which allows for halogen bonds to form. Iodine is especially good for XB as its large electron cloud distorts its electrons to create a partially positive region or sigma-hole. Each compound combination should produce cocrystals with different properties and uses. Our research aimed to explore these different outcomes through X-ray diffraction and temperature analysis. The results of these experiments can benefit various scientific fields, such as crystal engineering, solid-state synthesis, and pharmaceuticals, as they rely on these intermolecular interactions and structures.
