title: 2,2'-[1,2-Phenyl-enebis(aza-nedi-yl)]di-aceto-nitrile.
abstract: The title compound, C10H10N4, shows chemical but not crystallographic C2 symmetry. The two cyano-methyl groups are located in an anti position with respect to the aromatic ring. In the crystal, mol-ecules form parallel ladder-like tapes linked through two N-H⋯N hydrogen bonds. Further weak intra-molecular N-H⋯N hydrogen bonding is responsible for the elongation of one of the Caromatic-N bonds.
