In the title compound, [CdI2(C18H12N6S2)]n, the 4,4′-di-4-pyridyl-2,2′-disulfanediyldipyrimidine (L) ligand bridges two CdII centers, forming polymeric zigzag chains extending along the b axis. The CdII ions are coordinated by two N atoms from two L ligands and two iodide anions in a distorted tetrahedral geometry.

Slowly added is the CH2Cl2 (5 ml) solution of ligand L (0.1 mmol) into the CdI2 (0.1 mmol) solution in methanol (10 ml). The mixture was kept on standing for three days to give single crystals suitable for X-ray diffraction analysis.
All H atoms were positioned geometrically and allowed to ride on their parent atoms, with C—H = 0.93 Å and 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. |

Over past few years, organic aromatic disulfide has received considerable attention due to both its conformational flexibility and axial chirality (Horikoshi et al., 2006). In our previous study, we have reported two one-dimensional ZnII and FeII coordination polymers with the ligand L ( = 2, 2'-dithiobis(4-pyridin-4-ylpyrimidine) (Zhu et al., 2009). Herein, we report new one-dimensional CdII coordination chain generated by althernative linking of Cd center and ligand L.
The CdII ion in the title complex adopts a tetrahedral coordination geometry completed by two N atoms from two ligands L [Cd1—N1 2.287 (3) Å; Cd1—N6 2.289 (4) Å] and two I anions [I1—Cd1 2.6938 (4) Å; I2—Cd1 2.6962 (4) Å]. In L, the C—S—S—C torsion angle is 84.1 (2)°.
