, showing the hydrogen-bonded tartrate monoanions crosslinked by water molecules, which act as donors and acceptors of hydrogen bonds. Atoms labelled with an asterisk (*), a hash symbol (#) or a dollar sign ($) are at the symmetry positions (−x, y − $[{1\over 2}]$ , −z + $[{1\over 2}]$ ), (x + 1, y, z) or (x + $[{1\over 2}]$ , −y + $[{3\over 2}]$ , −z), respectively. Hydrogen bonds are shown as dashed lines and H atoms not involved in the interactions have been omitted.
