There are two 5-amino-1,3,4-thia­diazole-2(3H)-thiolate anions in the asymmetric unit of the title compound, Na+·C2H2N3S2·2H2O, which are almost perpendicular to each other [dihedral angle = 84.64 (6)°]. The two Na+ cations are in distorted fourfold coordinations by O atoms of the water molecules. The crystal structure is stabilized by N—H...S, O—H...N and O—H...S hydrogen bonds.

Comment top

Interest in the study of 5-amino-1,3,4-thiadiazole-2(3H)-thione derivatives stems from their use as intermediates of pharmaceuticals (John et al., 1960; John, 1962). Nonetheless, there are few articles that describe this kind of crystal structure (Downie et al., 1972; Deng et al., 2005; Ma et al., 2007). As part of our studies of agrochemicals, the title compound 5-amino-2-thione-1,3,4-thiadiazole sodium dihydrate has been synthesized, and its crystal structure is reported in this article. The complex is located across an inversion centre, and is bridged by two symmetry equivalent water molecules Na—O (bridge) distances of 2.3776 (14) Å and 2.5141 (15) Å and an Na—O—Na bond angle of 98.99 (3)°. It has two 5-amino-1,3,4-thiadiazole-2(3H)-thione molecules in the asymmetric unit that are almost perpendicular to each other [dihedral angle = 84.64 (6)°]. The structure is stabilized by N—H···S, O—H···N and O—H···S hydrogen bonds.

For use of 5-amino-1,3,4-thiadiazole-2(3iH/i)-thione derivatives as intermediates for pharmaceuticals, see: John et al. (1960); John (1962); For related structures, see: Downie et al. (1971); Deng et al. (2005); Ma et al. (2007).

Experimental top

5-amino-1,3,4-thiadiazole-2(3H)-thione(0.1 mmol) and sodium hydroxide (0.1 mmol) were dissolved in water (10 ml) and stirred for 3 h. The water was then removed under reduced pressure. Single crystals were obtained by slow evaporation of a methanol solution at room temperature.

Refinement top

All H atoms were initially located in a difference Fourier map. N-bound H atoms were located in a difference map and refined with an N—H distance restraint of 0.86 (1) Å. The water H atoms were refined using a riding model, with Uiso(H)=1.5eq(O).

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 > 2σ(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.
