Abstract: The structure of the title compound, [Li2(C8H2N2O8)(H2O)4]·H2O, is composed of dinuclear molecules in which the ligand bridges two symmetry-related LiI ions, each coordinated also by two water O atoms, in an O,N,O'-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 LiI 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.
