title: 2-Amino-4-(4-chloro-phen-yl)-5,6,7,8,9,10-hexa-hydro-benzo[8]annulene-1,3-dicarbonitrile.
abstract: In the title compound, C(20)H(18)ClN(3), the cyclo-octene ring exhibits conformational disorder of two methyl-ene groups with a site-occupation factor of 0.859 (6) for the major occupied site. In the crystal, mol-ecules are connected into inversion dimers via pairs of weak N-H⋯N hydrogen bonds, forming an R(2) (2)(12) graph-set motif. These dimers are further connected via weak N-H⋯Cl inter-actions into chains running along [011]. There are also C-H⋯N interactions present in the crystal.
