-iodido-dicopper(I)(Cu-Cu)]bis(
-4,4'-di-3-pyridyl-2,2'-disulfanediyldipyrimidine)]The title complex, [Cu2I2(C18H12N6S2)2]n, contains a Cu2I2 core with a Cu-Cu distance of 2.6935 (14) Å. The CuI atom is coordinated by two bridging 4,4'-di-3-pyridyl-2,2'-disulfanediyldipyrimidine ligands and two bridging I atoms, forming a double chain.
A CH2Cl2 solution (5 ml) of ligand L (0.1 mmol) was slowly added into a CuI (0.1 mmol) solution in acetonitrile (10 ml). The mixture was kept on standing for 3 d to give single crystals suitable for X-ray diffraction analysis.
H atoms were positioned geometrically and refined as riding atoms, with C—H = 0.93 Å and Uiso(H) = 1.2Ueq(C). The highest residual electron density was found 0.98 Å from I1 and the deepest hole 0.92 Å from I1.

In recent years, heterocyclic disulfide ligands have received increasing attention because of their conformationally defined dihedral angle (Horikoshi & Mochida, 2006). As continuation of our previous research (Zhu et al., 2009), we report here a copper(I) coordination polymer with a 2,2'-dithiobis(3-pyridin-4-ylpyrimidine) (L) ligand.
The CuI atom in the title complex has a tetrahedral coordination geometry completed by two N atoms from two different L ligands and two bridging I atoms (Fig. 1 and Table 1). The C—S—S—C torsion angle of 81.2 (2)° in L is almost identical with the free molecule (Ji et al., 2009). Alternative linkings of one Cu2I2 core and two bridging L ligands generate a one-dimensional double chain (Fig. 2).
