3,4,7,8-Tetramethyl-1,10-phenanthrolin-1-ium nitrate monohydrate

Abstract

In the crystal of the title compound, C16H17N2 +·NO3 −·H2O, the tetramethyl-1,10-phenanthrolinium cations, nitrate anions and lattice water molecules are all located on a mirror plane with the methyl H atoms of the cation equally disordered over two sites about the mirror plane. The cation, anion and water molecule are linked by O—H...O and N—H...O hydrogen bonds into a sheet parallel to the bc plane. π–π stacking between phenanthroline ring systems is observed in the crystal structure, the centroid–centroid distance being 3.4745 (6) Å.
