In the crystal structure of the title compound, C(12)H(8)Cl(4)N(2), mol-ecules lie on crystallographic twofold axes at the centre of the C-C bonds linking the benzene rings, such that the asymmetric unit consists of a half-mol-ecule. The individual mol-ecules participate in inter-molecular N-H⋯N, N-H⋯Cl, C-H⋯Cl and Cl⋯Cl [3.4503 (3) Å] inter-actions.
