Abstract

In the crystal structure of the title compound, 2C6H 4N2·C6H8Cl2O 4·2C2H3N, the two symmetry-related pyridine-3-carbonitrile mol-ecules are linked to either side of a chloranilic acid (systematic name: 2,5-dichloro-3,6-dihydr-oxy-1,4-benzoquinone) mol-ecule via inter-molecular O- H⋯N hydrogen bonds, giving a centrosymmetric 2:1 unit. The dihedral angle between the pyridine ring and the chloranilic acid plane is 26.71 (6)°. In addition, the two acetonitrile mol-ecules are linked to either side of the 2:1 unit through C- H⋯N hydrogen bonds, forming a 2:1:2 aggregate. These 2:1:2 aggregates are further linked by weak inter-molecular C- H⋯N and C- H⋯O hydrogen bonds, forming a tape along the c axis.
