Dimethylpiridine and Dimethylpyrazine: X-Ray Diffraction of Cocrystals

Our focus for the summer research project was on the use of noncovalent interactions between molecules to design cocrystals. This design was by taking various forms of Dimethylpyrazine and Dimethylpyridine or various N-oxide chemicals and mixing them with other chemicals to create a new cocrystals not seen in literature before. We hope this research can contribute to a better environment along with advancing pharmaceutical research. During our summer research we studied the structure-property relationships in various cocrystals in order to determine numerous systematic trends in their physical and chemical properties. We were able to see the structures of these crystals thanks to X-ray diffraction, which bounced light off the crystals to map the placement of the molecules that made it up. Some short conclusions we found were that Iodine can become very unstable in the dark and cold, and that acetone can also become very reactive in the dark and cold when paired with Iodine.
