| Abstract: | The complex formation in the system bis[2-(trimethylammonio)ethyl] succinate diodide-iodine involves no more than two iodine molecules. The crystal structure of the salt [(CH3)3N(CH2)2OCOCH2]2(I3)2 is formed by layers of inorganic anions (I3-) and organic dications (centrosymmetric dications {[(CH3)3N · (CH2)2OCOCH2]+}2), evenly alternating along the a axis. The crystal structure of the salt [(CH3)3N(CH2)2·OCOCH2]2(I3)2(I2)0.5 is formed by organic and inorganic layers evenly alternating along the [011] diagonal, with a centrosymmetric iodine molecule. |
