Abstract

The hydrogen-bonded 1:2 complexes of chloranilic acid (2,5-dichloro-3,6-dihydroxy-p-benzoquinone) with pyrimidine [(1), C₆H₂Cl₂O₄·2C ₄H₄N₂] and pyrazine [(2), C₆H₂Cl₂O₄·2C ₄H₄N₂] were prepared and their crystal structures determined at room temperature. In both complexes, the chloranilic acid molecules lie on inversion centres and in each complex, the two components are held together by O - H⋯N hydrogen bonds with short O⋯N distances of 2.615 (2) Å for (1) and 2.590 (4) Å for (2).
