title: Second monoclinic modification of cyclo-hexane-1,1-dicarbonitrile.
abstract: In the title compound, C(8)H(10)N(2), the cyclo-hexane ring adopts a chair conformation. he crystal structure of the previously reported monoclinic modification have intramolecular CN⋯CN and C-H⋯N interactions. These types of interaction are not present in this new modification whose crystal structure is built up by van der Waals interactions.
