Abstract: The asymmetric unit of the title compound, [Li4(C5H3N2O2)2(H2O)5]Cl2, contains two LiI cations, one with a distorted trigonal-bipyramidal and the other with a distorted tetrahedral coordination geometry. Two symmetry-related asymmetric units constitute a building block of the structure, in which both ligand carboxylate O atoms are bidentate and bridge the metal ions, forming a divalent cation. Charge balance is maintained by two chloride anions. The building blocks, bridged by LiI cations, form cationic ribbons with chloride anions in the space between them. The ribbons propagate in [010] and are held together by a network of weak O-H...O hydrogen bonds which operate in the space between adjacent ribbons.
