Crystal structure of 4-benzyl-carbamoyl-1-methyl-pyridin-1-ium iodide: an efficient multimodal anti-viral drug.

ABSTRACT: In the title compound, [MeC₅H₄NCONHCH₂C₆H₅]I or C₁₄H₁₅N₂O⁺·I^-, a cation and an anion form an ionic pair linked by a strong N-H⋯I hydrogen bond. In the crystal, ionic pairs linked by weak C-H⋯I hydrogen bonds form infinite ribbons along the crystallographic a axis. Polymorphism screening varying crystallization solvents (water, acetone 90%-water, ethanol 90%-water, 2-propanol 90%-water, DMF, DMSO, methanol, aceto-nitrile) and conditions (solution temperature, heating and cooling protocols) did not reveal any other polymorphs than the one reported in this work.
