A coordination polymer [Ba(pcmb)(H 2 O) 2.5 ] ( 1 ) was obtained by self‐assembly of the corresponding metal carbonate with a flexible ligand, p ‐(carboxyl‐methyloxy)‐benzenecarboxylic acid (H 2 pcmb), and its structure was determined by single‐crystal X‐ray diffraction studies. The result revealed that complex 1 has a three‐dimensional structure, in which the barium(II) atom takes a distorted eight‐coordinate bicapped anti ‐prism arrangement. The pcmb 2– anion acts as a μ 4 ‐bridge ligand, in which carboxylate groups adopt monodentate and μ 3 ‐ η 2 : η 1 ‐bridging two different coordination models to generate a three‐dimensional network structure. The luminescence property and thermal stability of 1 were investigated.
