Figure 12
Part of the crystal structure of (III), showing the tartrate monoanions crosslinked by the protonated amino groups of the cystamine cation. Atoms labelled with an asterisk (*), a hash symbol (#) or a dollar sign ($) are at the symmetry positions (x, y − 1, z), (x + 1, y − 1, z) or (x + 1, y, z). Hydrogen bonds are shown as dashed lines and H atoms not involved in the interactions have been omitted. |
