| Summary: | The structure of the title compound, [Li(C5H3N2O2)(H2O)]n, contains an LiI ion with a distorted trigonal–bipyramidal coordination environment involving the N and O atoms of pyrazine-2-carboxylate ligands with a bridging carboxylate group, and two aqua O atoms also in a bridging mode. The symmetry-related LiI ions bridged by a carboxylate O atom and a coordinating water O atom form an Li2O2 unit with an Li...Li distance of 3.052 (4) Å, which generates molecular ribbons propagating in the c-axis direction. The ribbons are held together by a network of O—H...O hydrogen bonds in which the coordinating water molecules act as donors and the carboxylate O atoms as acceptors. |
