rac-1,2,3,4-Tetrahydro-1,4-methanoanthracene-6,7-dicarbonitrile

Abstract

The title compound, C17H12N2, comprises a norbornane unit having a dicyanonaphthalene ring fused on one side. Both cyano groups are twisted slightly out of the plane of the naphthalene ring system [C—C—C—C torsion angle = 1.9 (2)°]. In the crystal, inversion-related molecules are linked by pairs of weak C—H...N hydrogen bonds, forming dimers.
