In the title compound, [Co(C5H3N4O)(N3)(H2O)]n, the cobalt ion is coordinated by three N atoms of two organic ligands, two N atoms of two azide anions and one water molecule in a distorted octahedral geometry. The metal atoms are connected via the ligands into layers, which are further connected by O—H⋯N and O—H⋯O hydrogen bonding.

A mixture of Co(II)nitrate (1.5mmol), 3H-[1,2,3]triazolo[4,5-b]pyridin-3-ol(0.75 mmol), and sodium azide (2mmol), in 10 ml MeOH solvent was sealed in a Teflon-lined stainless-steel Parr bomb that was heated at 413 K for 48 h. Red crystals of the title complex were collected after the bomb was allowed to cool to room temperature. Yield 20% based on metal salt.
Hydrogen atoms of water molecule were added by difference Fourier maps and refined directly. Other hydrogen atoms were included in calculated positions and treated as riding on their parent C atoms with C—H = 0.93Å and Uiso(H) = 1.2Ueq(C).

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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. |

Azide anion has drawn much attentions because they can coordinate to metal ions in diverse coordination modes (Zeng, et al., 2009). Therefore, several metal azide complexes with different co-ligand has been prepared and characterized (Wang, et al., 2008). As a part on a project of new metal azide coordination polymers the structure of the title compound was determined.
In the crystal structure of the title compound the Co ions are coordinated by two N atoms of two symmetry related azide anion, three N atoms of two symmetry related organic ligands and one water molecule within slightly distorted octahedra (Fig. 1). The Co ions are connected via two end-on bridging thiocyanato anions into chains, that are further be connected into layers by the organic ligands. These layers are located in the b-c-plane and are linked via N-H···O and N-H···N hydrogen bonding to adjacent water molecules and azide anions (Fig. 2).
