摘要：

The hydrogen-bonded 1:2 complexes of chloranilic acid (2,5-dichloro-3,6-dihydroxy-p-benzoquinone) with pyrimidine [(1), C6H2Cl2O4. 2C(4)H(4)N(2)] and pyrazine [(2), C6H2Cl2O4. 2C(4)H(4)N(2)] 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 shore O ... N distances of 2.615 (2) Angstrom for (1) and 2.590 (4) Angstrom for (2).
