[1-(4-Hydroxy­phen­yl)-1H-tetra­zol-5-ylsulfan­yl]acetic acid

Abstract

The title compound, C₉H₈N₄O₃S, shows a layer structure constructed from inter­molecular O—H⋯O and O—H⋯N hydrogen bonds. Inter­atomic distances suggest that extensive, but not uniform, π-electron delocalization is present in the tetra­zole rings and extends over the exocyclic C—S bond.

Comment

Tetrazol-5-thione and its derivatives are interesting ligands from a structural point of view since they can display a wide range of coordination patterns with metal ions. Due to a variety of potential coordination sites, they can act as monodentate (–S or –N) or bidentate (–N, N or –N, S) ligands, forming polymers or interacting with metal ions (Cea-Olivares et al., 1997; Kim et al., 2003).

As shown in Fig.1, the bond lengths within the tetrazole ring exhibit the expected pattern of four long bonds (C7—N1, C7—N4, N3—N4 and N1—N2) together with a short one (N2—N3). In detail, C7—N1 [1.340 (2) Å] and C7—N4 [1.324 (2) Å] are typical for carbon-nitrogen single bonds from 1.336 Å to 1.420 Å, while N3—N4 [1.365 (2) Å] and N1—N2 [1.358 (2) Å] are between the single and double bonds. And the bond distance N2—N3 of 1.283 (2) Å is similar to that of a double bond of 1.25 Å. The bond length of S1—C7 [1.723 (2) Å9 also falls between the double and single bonds. All these interatomic distances suggest that extensive but not uniform π electron delocalization is present in the tetrazole rings and extends over the exocyclic C—S bond.

Experimental

To an aqueous solution of 1-(4-hydroxyphenyl)-5-thiotetrazole (1.940 g, 10.0 mmol) and NaOH (0.80 g, 20.0 mmol) were sequentially added the aqueous solution of chloroactic acid (2.835 g, 30.0 mmol) and NaOH (1.400 g, 35.0 mmol). After stirring for 4 h at 353 K under nitrogen atmosphere, the mixture was cooled to room temperature slowly. Adjusted the pH to 2 by adding 1.0 mol/L HCl, the white deposit appeared rapidly. The solids were filtered and washed with water. The single crystals suitable for X-ray diffraction were obtained by the re-crystallization of sieved solid in the ethanol.

Refinement

The H atoms bonded to C atoms were positioned geometrically and treated as riding, [aromatic C—H = 0.93 Å and aliphatic C—H = 0.97 Å, U_iso(H) = 1.2U_eq(C)]. The H atoms bonded to O atoms were located in a difference Fourier map and refined isotropically.

Special details

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.
