Conclusion
The new monoclinic modification of cyclohexane-1,1-dicarbonitrile lacks certain interactions present in a previously reported form and is stabilized by van der Waals interactions.
Supporting Evidence
- The cyclohexane ring in the compound adopts a chair conformation.
- The new modification does not exhibit intramolecular CN⋯CN and C—H⋯N interactions.
- The crystal structure is primarily stabilized by van der Waals interactions.
Takeaway
Scientists discovered a new version of a chemical compound that doesn't interact the same way as an older version, making it more stable in a different way.
Methodology
The compound was synthesized using a reaction of malonodinitrile and 1,5-dibromopentane in dry DMSO, followed by purification and crystallization.
