(Received 26 December 2009; accepted 1 January 2010; online 13 January 2010)

There are two monomeric units in the asymmetric unit of the polymeric title compound, [Na(C5H4NOS)(C10H8N2O2S2)(H2O)]n. The NaI ions are six coordinated by four O atoms, one S atom and one water mol­ecule, forming a slightly distorted octa­hedral geometry. An intra­molecular O—H⋯O hydrogen bond stabilizes the conformation of the mol­ecule. The crystal packing is consolidated by inter­molecular O—H⋯O, O—H⋯N and O—H⋯S hydrogen bonds, ππ inter­actions [with centroid–centroid distances of 3.587 (2) Å] together with weak C—H⋯π inter­actions. The mol­ecules are linked into polymeric chains along the b-axis direction.

Comment top

N-oxides and their derivatives show a broad spectrum of biological activity such as antifungal, antimicrobial and antibacterial activities (Lobana & Bhatia, 1989; Symons et al., 1985). These compounds are also found to be involved in DNA strand scission under physiological conditions (Katsuyuki et al., 1991; Bovin et al., 1992). Pyridine N-oxides bearing a sulfur group in position two display significant antimicrobial activity (Leonard et al., 1955). In view of the importance of N-oxides, we have previously reported the crystal structures of N-oxide derivatives (Jebas et al., 2005; Ravindran et al., 2008). As an extension of our work on N-oxide derivatives, we report here the crystal structure of the title compound (I).

In the asymmetric unit of (I)(Fig 1), the NaI ion is six coordinated by four oxygen atoms, two from 1-oxypyridine-2-thiolato and two from 2,2-thiobis(pyridine N-oxide) ligands, and one sulfur atom from 1-oxypyridine-2-thiolato ligand. The pyridyl rings are essentially planar with the maximum deviation from planarity of -0.034 (5) Å for atom C10. The N–O bond lengths are in good agreement with the mean value of 1.304 (15) Å reported in the literature for pyridine N-oxides.

Intramolecular O—H···O hydrogen bonding influence the conformation of the molecule. The crystal packing (Fig 2) is consolidated by intermolecular O—H···O, O—H···N and O—H···S hydrogen bonding together with intramolecular S···O= 2.587 (3) to 3.069 (3) Å; N···S=2.686 (4) to 2.700 (5) Å; S···Na=3.807 (2) Å, intermolecular S···Oi=3.065 (3) Å, O···Oi=2.784 (3), O···Oii=2.798 (3) Å, intramolecular S···O =2.587 (3)to 3.069 (3) Å; O···O = 2.784 (3) to 2.798 (3) Å; S···Na=3.807 (2) Å and N···S=2.686 (4) to 2.700 (5) Å short contacts [symmetry code: (i) 1/2+X,1-Y,Z (ii) -1/2+X, 1-Y, Z]. ππ interactions with cg1-cg4iii=3.587 (2)Å (Where Cg1 is N1/C2—C6; Cg2 is N25/C26—C30) [symmetry code: (iii) X, -1+Y, Z] together with weak C—H··· π interactions. The molecules are linked into polymeric chains along the b-direction.

Experimental top

A mixture of Sodium salt of 1-hydroxypyidine-2-thione (0.298 2mmol), ethanol (10 ml)and sodium ethoxide (10ml) was heated at 333 K with stirring for 30 min. After two days again Sodium salt of 1-hydroxypyidine-2-thione(0.149,1mmol)was added. The solution was again heated at 333 K with stirring for 30 min. The mixture was then kept aside for slow evaporation. After a week colourless crystals were formed.

Refinement top

After checking their presence in the Fourier map, all the aromatic hydrogen atoms were fixed on the calculated positions and allowed to ride on their parent atoms with the C—H = 0.95 Å. The water hydrogen atoms were located from the Fourier map and allowed to refine freely with the distances O—H = 0.86 to 0.92Å (water) with Uiso(C) in the range of 1.2Uequ(C) and 1.5Uequ(O) water. The crystal was an inversion twin. The Flack parameter indicates the fractional contribution of the twin components.

Special details top

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.
