Crystal structure of 4-benzyl­carbamoyl-1-methyl­pyridin-1-ium iodide: an efficient multimodal anti­viral drug

In the title compound, [MeC(5)H(4)NCONHCH(2)C(6)H(5)]I or C(14)H(15)N(2)O(+)·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, aceto­nitrile) and conditions (solution temperature, heating and cooling protocols) did not reveal any other polymorphs than the one reported in this work.
