Figure 8
Part of the crystal structure of (II), showing the tartrate anions crosslinked by the protonated amino groups of the cystamine dication. Atoms labelled with an asterisk (*), a hash symbol (#), a dollar sign ($) or an ampersand (&) are at the symmetry positions (−x + 2, y + , −z + ), (x − 1, y, z), (x − , −y + , −z) or (x − , −y + , −z), respectively. Hydrogen bonds are shown as dashed lines and H atoms not involved in the interactions have been omitted. |
