• The crystal structure of an organic charge-transfer complex, 1-ethyl-2-methylquinolinium iodide, [(C<SUB>12</SUB>H<SUB>14</SUB>N)<SUP>+</SUP>·I<SUP>−</SUP>], has been determined by means of three-dimensional X-ray data (Mo<I>K</I>α). The crystals are monoclinic, space group <I>P</I>2<SUB>1</SUB>/<I>c</I>, and have four formula units in a unit cell with the dimensions of <I>a</I>=7.187±0.002, <I>b</I>=15.914±0.002, <I>c</I>=10.331±0.002 Å, and β=94.67±0.01°. The structure is built up from an iodide anion and a planar 1-ethyl-2-methylquinolinium cation, which lie roughly on a plane. The cations are stacked approximately parallel to the <I>a</I>-plane, forming an endless column along the <I>a</I> axis; the interplanar spacings of these cations are alternately 3.4 and 3.6 Å. The iodide anions are located in the spaces between these columns and the ethyl groups of the cations. The closest distance between an iodide anion and the carbon atoms of a 1-ethyl-2-methylquinolinium ring is 3.93 Å.
