| Summary: | In cold methanol, energetic ionic liquid 1-n-propyl-3-vinyl-imidazol-1-ium perchlorate, <b>1</b>, crystallizes in the presence of excess Ba(ClO<sub>4</sub>)<sub>2</sub>, <b>2</b>, into tetrakis 1-propyl-3-vinyl-imidazol-1-ium·barium hexa-perchlorate, <b>3</b>. Crystals of <b>3</b>, with molecular formula (C<sub>8</sub>H<sub>13</sub>N<sub>2</sub>)<sub>4</sub>·BaCl<sub>6</sub>O<sub>24</sub>, are colorless and monoclinic, with space group P2<sub>1</sub>/c. The crystal structure is characterized by a dodecahedral coordination around the barium atom, with each perchlorate chelating Ba<sup>2+</sup> in a κ<sup>2</sup>O,O’ fashion, and the Ba(ClO<sub>4</sub>)<sub>6</sub><sup>4−</sup> anion is surrounded by four imidazolium cations. |
