Bis(triethylammonium) chloranilate

Abstract

In the crystal structure of the title compound [systematic name: bis(triethylammonium) 2,5-dichloro-3,6-dioxocyclohexa-1,4-diene-1,4-diolate], 2C6H16N+·C6Cl2O42−, the chloranilate anion lies on an inversion center. The triethylammonium cations are linked on both sides of the anion via bifurcated N—H...(O,O) and weak C—H...O hydrogen bonds to give a centrosymmetric 2:1 aggregate. The 2:1 aggregates are further linked by C—H...O hydrogen bonds into a zigzag chain running along [01-1].
