Part of the crystal structure of (I)

, showing the head-to-tail hydrogen-bonded chains of tartrate monoanions crosslinked by the protonated amino group of the cysteamine cation. One of the three hydrogen bonds is bifurcated. Atoms labelled with an asterisk (*), a hash symbol (#) or a dollar sign ($) are at the symmetry positions (x + 1, y, z), (−x + 2, y + $[{1\over 2}]$ , −z + $[{1\over 2}]$ ) or (−x + 1, y + $[{1\over 2}]$ , −z + $[{1\over 2}]$ ), respectively. Hydrogen bonds involving the amino groups are shown as dashed lines and H atoms not involved in the interactions have been omitted.
