Abstract
The two iodide salts, 4-[(benzyl-amino)-carbon-yl]-1-methyl-pyridinium iodide-iodine (2/1), C14H15N2O+·I-·0.5I2, I, and 4-[(benzyl-amino)-carbon-yl]-1-methyl-pyridinium 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 mol-ecule 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.
