The title compound, C30H20N6O4Cl4.2C16H36N+·2Cl−·2C2H3N, contains two hydrogen-bonded chloride anions bound to 1,4-phenylene-bis-(3,4-dichloro-5-phenylcarbamoyl-1H-pyrrole-2-carboxamide) as the tetrabutylammonium salt. There is also a short pyrrolic hydrogen bond (NCl = 3.068 (3) Å), and two longer ones to the amino H atoms [NCl = 3.269 (3) Å and 3.275 (3) Å]. The neutral molecule lies on an inversion centre situated at the centre of the central benzene ring.
