J. Pickardt et B. Kuhn, REACTION OF MERCURIC IODIDE WITH CRYPTAND-222 - CRYSTALLOGRAPHIC EVIDENCE FOR THE FORMATION OF FINITE OCTAIODOTRIMERCURATE(II) IONS [HG3I8](2-), Journal of the Chemical Society, Chemical Communications, (4), 1995, pp. 451-452
By the reaction of solutions of Hgl(2) and cryptand 222, crystals of a
compound consisting of [Hg(cryptand 222)](2+) cations and previously
unreported discrete [Hg(3)l(8)](2-) anions are obtained, and are chara
cterized by single crystal X-ray diffraction.
