N2 - The hydrogen-bonded 1:1 complexes of chloranilic acid (2,5-dichloro-3,6-dihydroxy-p-benzoquinone) with pyrazine (1,4-diazine), pyrazine-chloranilic acid (1/1), C4H4N2·C6H2Cl 2O4, (1), and with morpholine, morpholinium chloranilate, C4H10NO+·C6HCl 2O-4, (2), were prepared and their crystal structures were determined at room temperature. The two components in (1) are linked by O - H⋯N hydrogen bonds to form a one-dimensional chain. In (2), molecules of chloranilic acid form an O - H⋯O hydrogen-bond chain and that of morpholine links the two chains with N - H⋯O hydrogen bonds, forming the two-dimensional hydrogen-bond network in the crystal.
