摘要：

The molecule of 1,2-dicyanobenzene, C8H4N2, possesses mirror symmetry. The two cyano groups are bent slightly above the plane of the molecule. The six aromatic C-C bonds in the benzene ring have a mean value of 1.377 Angstrom. The C-CN and C=N bond lengths are 1.430(7) and 1.149(8)Angstrom, respectively. The internal angles in the benzene ring differ slightly from 120 degrees. The shortest intermolecular contact is N(1)... H(2) of 2.657 (16)Angstrom.
