In the title 3)(C11H9N5)]n, the unique CdII ion is coordinated in a distorted pentagonal–bipyramidal environment. The axial thiocyanate ligands act in a μ1,3-bridging mode to connect symmetry-related CdII ions into one-dimensional chains along [010]. In addition, there are intermolecular C—H⋯O contacts between chains.

A 15 ml methanol solution containing 2,6-bis(pyrazolyl)pyridine (0.4140 g, 0.196 mmol) was added to 8 ml H2O solution of Cd(NO3)26H2O (0.0689 g, 0.200 mmol) and NaSCN (0.0324 g, 0.400 mmol), and the mixture was stirred for a few minutes. Colorless single crystals were obtained after the filtrate was allowed to stand at room temperature for a month.
All H atoms were placed in calculated positions with C—H = 0.93 Å and refined as riding with Uiso(H) = 1.2Ueq(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. |

Both the 2,6-bis(pyrazolyl)pyridine and thiocyanate ligands play an important role in modern coordination chemistry (Halcrow 2005; Shi et al. 2006), and our interest in complexes formed with these ligands led us to prepare the title complex and determine its crystal structure (I).
As shown in Fig. 1 the CdII ion is coordinated in a distorted pentagonal–bipyramidal environment with the 2,6-bis(pyrazolyl)pyridine and nitrate anion acting as chelating tridentate and bidentate ligands, respectively. The axial thiocyantate ligands bridge symmetry-related CdII ions [with a Cd···Cd separation of 6.1817 (10) Å] to form a one-dimensional `zigzag' chain along the b axis (Fig. 2). In addition, the crystal structure contains C—H···O and C—H···S short contacts between chains.
