Özet

Schiff base-metal complexes have been used widely as catalysts for many organic reactions, such as ring-opening polymerization and oxidation. In view of the importance of Cd-II coordination polymers and in an effort to enlarge the library of such complexes, the title novel polymeric Cd-II tridentate Schiff base complex, [Cd-3(C13H16BrN2O)(2)Cl-4(CH4O)(2)](n), has been synthesized and characterized by elemental analyses, UV and IR spectroscopies, and single-crystal X-ray diffraction. The complex crystallizes in the triclinic P<()over bar> space group with two symmetry-independent Cd-II atoms, one of which lies on an inversion centre, and analysis of the crystal structure shows that both Cd-II atoms are six-coordinated; the environment around one Cd-II atom can be described as distorted octahedral, while that around the second Cd-II atom is octahedral. The Cd-II atoms are linked by chloride ligands to form a one-dimensional coordination polymer. The nonbonding intermolecular Cd center dot center dot center dot Cd distances are 3.7009 (4) and 4.3563 (5) angstrom. Furthermore, the photoluminescence properties of the complex have been investigated and it displays a strong red emission in the solid state at room temperature.
