title: 1,4-Diazo-niabicyclo-[2.2.2]octane bis-(2-chloro-benzoate).
abstract: The title compound, C(6)H(14)N(2) (2+)·2C(7)H(4)ClO(2) (-), contains trimeric units linked by N-H⋯O hydrogen bonds. The carboxyl-ate groups of the 2-chloro-benzoate anions form dihedral angles of 66.1 (1) and 76.1 (1)° with the respective chloro-benzene rings to which they are bound. The hydrogen-bonded trimers are arranged in layers in the (200) planes and the chloro-benzoate anions form edge-to-face inter-actions between layers, with dihedral angles of 61.9 (1) and 49.8 (1)° and centroid-centroid distances of 4.85 (1) and 4.65 (1) Å, respectively, for two crystallographically distinct inter-actions.
