(Received 20 November 2009; accepted 27 November 2009; online 4 December 2009)

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

Comment top

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 Zn^II and Fe^II coordination polymers with the ligand L ( = 2, 2'-dithiobis(4-pyridin-4-ylpyrimidine) (Zhu et al., 2009). Herein, we report new one-dimensional Cd^II coordination chain generated by althernative linking of Cd center and ligand L.

The Cd^II 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)°.

Experimental top

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.

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.
