title: Butane-1,4-diaminium bis-[3,4,5,6-tetra-chloro-2-(meth-oxy-carbon-yl)benzoate].
abstract: In the title salt, C(4)H(14)N(2) (+)·2C(9)H(3)Cl(4)O(4) (-), the cation lies on an inversion center. In the anion, the mean planes of meth-oxy-carbonyl and carboxyl-ate groups form dihedral angles of 64.9 (3) and 58.5 (3)°, respectively, with the benzene ring. In the crystal, inter-molecular N-H⋯O hydrogen bonds connect the components into sheets parallel to (100).
