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 (C 13 H 16 BrN 2 O) 2 Cl 4 (CH 4 O) 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 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…Cd distances are 3.7009 (4) and 4.3563 (5) Å. Furthermore, the photoluminescence properties of the complex have been investigated and it displays a strong red emission in the solid state at room temperature.
