4-Dimethylaminopyridinium picrate: supramolecular aggregation through extensive N-HO and C-HO interactions

N. Vembu, M. Nallu, J. Garrison and W. J. Youngs

Abstract: The crystal structure of the title compound, C₆H₂N₃O₇·C₇H₁₁N₂, contains two 4-dimethylaminopyridinium cations and two picrate anions in the asymmetric unit. The N-HO and C-HO interactions generate rings of graph set motifs S(5), R²₁(6), R¹₂(5), R²₁(4), R¹₂(7), R¹₂(6), R²₂(8), R²₂(10) and R²₂(14), which contribute to the supramolecular aggregation through bifurcated and trifurcated bonds.
