title: 7-Chloro-4-(piperazin-1-yl)quinoline.
abstract: There are two mol-ecules in the asymmetric unit (Z' = 2) of the title compound, C(13)H(14)ClN(3), Each mol-ecule is linked by N-H⋯N hydrogen bonds to another of the same type in a chain in [110]. The crystal studied was a non-merohedral twin with components 0.622 (2) and 0.378 (2).
