Figure 2
Part of the crystal structure of (I), showing (a) the formation of the anion sheet and (b) the linking of the cations to the anion sheet. For clarity, the hydrocarbyl component of the cations and H atoms bonded to C atoms in the anions have been omitted. Atoms marked with an asterisk (*), a hash (#), a dollar sign ($) or an ampersand (&) are at the symmetry positions (1 − x, 1 − y, 1 − z), (1 − x, − + y, − z), (x, − y, − + z) and (1 − x, + y, − z), respectively. |
