N2 - In the crystal structure of the title compound, C7H 11N2+·C11H9N 2O3-, both the cation and the anion lie on a mirror plane. Three C atoms of the butyl group are disordered over two positions related by this plane. The bond-length analysis shows that the surplus negative charge of the anion is delocalized between the cyclobutene ring and the dicyanomethylene group. The 4-dimethylaminopyridinium cation has an intermediate aromatic-quinoid structure.
