Nicotinium picrate

K. Anitha, S. Athimoolam and R. K. Rajaram

Abstract: The title compound, C6H6NO2+·C6H2N3O7-, is the picrate salt of the nicotinium cation. In the picrate anion, the ortho nitro groups are twisted out of the plane of the ring, whereas the para nitro group lies approximately in the ring plane. Hydrogen bonds from the nicotinate cation link two different picrate anions, forming a straight chain along the b axis. The picrate anions are stacked in columns along [010].
