Aqua-bis-[N'-(1,3-dithio-lan-2-ylidene)-2-hy-droxy-benzohydrazidato(0.5-)-κ(2)N',O]sodium(I).

The title compound, [Na(C(10)H(9.5)N(2)O(2)S(2))(2)(H(2)O)], is a mol-ecular sodium complex with N'-(1,3-dithio-lan-2-yl)-2-hy-droxy-benzohydrazide ligands with the negative charge spread evenly over both, and a water mol-ecule. The Na(I) ion coordination is distorted trigonal-bipyramidal, formed by two N and three O atoms, with the Na(I) ion lying on a twofold rotation axis. Intra-molecular N-H⋯O hydrogen bonds occur. Mol-ecules 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 inter-linked by strong O-H⋯O hydrogen bonds.
