The title compound, [Na(C10H9.5N2O2S2)2(H2O)], is a mol­ecular sodium complex with N′-(1,3-dithio­lan-2-yl)-2-hy­droxy­benzohydrazide ligands with the negative charge spread evenly over both, and a water mol­ecule. The NaI ion coordination is distorted trigonal–bipyramidal, formed by two N and three O atoms, with the NaI ion lying on a twofold rotation axis. Intra­molecular N—H⋯O hydrogen bonds occur. Mol­ecules pack as discrete units and the crystal packing is stabilized by strong O—H⋯O hydrogen bonds, which give rise to chains along [010]; the chains are inter­linked by strong O—H⋯O hydrogen bonds.
