Description:
<jats:p>The structure of the title compound, [Li<jats:sub>2</jats:sub>(C<jats:sub>8</jats:sub>H<jats:sub>2</jats:sub>N<jats:sub>2</jats:sub>O<jats:sub>8</jats:sub>)(H<jats:sub>2</jats:sub>O)<jats:sub>4</jats:sub>]·H<jats:sub>2</jats:sub>O, is composed of dinuclear molecules in which the ligand bridges two symmetry-related Li<jats:sup>I</jats:sup>ions, each coordinated also by two water O atoms, in an<jats:italic>O</jats:italic>,<jats:italic>N</jats:italic>,<jats:italic>O</jats:italic>′-manner. The Li and N atoms occupy special positions on twofold rotation axes, whereas a crystal water molecule is located at the intersection of three twofold rotation axes. The Li<jats:sup>I</jats:sup>cation shows a distorted trigonal–bipyramidal coordination. Two carboxylate groups remain protonated and form short interligand hydrogen bonds. The molecules are held together by a network of hydrogen bonds in which the coordinating and solvation water molecules act as donors and carboxylate O atoms as acceptors, forming a three-dimensional architecture.</jats:p>
