| Popis: | The ability of 4-[(benzylamino)carbonyl]-1-methylpyridinium to form iodide salts with cation:iodine ratio different from equimolar was studied and a Hirshfeld surface analysis was performed to investigate the intermolecular interactions. The two iodide salts, 4-[(benzylamino)carbonyl]-1-methylpyridinium iodide–iodine (2/1), C14H15N2O+·I−·0.5I2, I, and 4-[(benzylamino)carbonyl]-1-methylpyridinium triiodide, C14H15N2O+·I3 −, II, with different cation:iodine atoms ratios were studied. Salt I contains one cation, one iodide anion and half of the neutral I2 molecule in the asymmetric unit (cation:iodine atoms ratio is 1:2). Salt II contains two cations, one triiodide anion (I 3 −) and two half triiodide anions (cation:iodine atoms ratio is 1:3). The NH group forms N—H⋯I hydrogen bonds with the I− anion in the crystal of I or N—H⋯O hydrogen bonds in II where only triiodide anions are present. |
