To a solution of 3-methylmercapto-5-mercapto-1,2,4-thiadiazole (10 mmol) in 60 ml of doubly-distilled water, a solution of an equimolar amount (10 mmol) of sodium hydroxide in 40 ml of doubly-distilled water was added dropwise at room temperature. After vigorous stirring for 6 h, the resulting mixture was evaporated in vacuo to a volume of about 20 ml and filtered hot. The filtrate was then set aside for crystallization at room temperature. Two weeks later, colourless single crystals suitable for X-ray diffraction were obtained.
H atoms of the water molecules were initially located a difference Fourier map and later refined using a riding model with O-H = 0.85Å and Uiso(H) = 0.05 Å2. C-bound H atoms were positioned geometrically and treated as riding on their parent atoms with C-H = 0.96 Å and Uiso(H) = 1.5Ueq(C).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

In the title compound (Fig.1), each Na+ ion has a six-coordinate environment formed by a S atom and a N atom of the 3-methylsulfanyl-1,2,4-thiadiazole-5-thiolate ligand, and four bridging water O atoms O1, O1A, O1B and O1C. The adjacent NaSNO4 units share O1···O1A and O1B···O1C edges, producing chains running along the b axis (Fig. 2). Similar chains were found in the crystal structure of sodium carboxynitrobenzoate tetrahydrate (Guo, 2004). The Na—O [2.4493 (16) and 2.4736 (16) Å], Na—S [3.1271 (14) Å] and Na—N [2.467 (2) Å] distances are comparable to those observed in a related structure (Wang et al., 2007).
