abstract: The hydro-thermal reaction of SrCO(3) and 2-bromo-benzoic acid in CH(3)OH-H(2)O afforded the Sr(II) title polymeric complex, [Sr(C(7)H(4)BrO(2))(2)(H(2)O)(2)](n). Within the coordination sphere, the Sr(II) ion is located on a crystallographic twofold axis, and is coordinated by eight O atoms from two water mol-ecules and four carboxyl-ate groups of 2-bromo-benzoate ligands in an irregular coordination geometry. Two μ(3)-carboxyl-ate groups of the 2-bromo-benzoate anions bridge two symmetry-related Sr(II) atoms, giving rise to a chain structure extending along [001]. The polymeric chains are connected via O-H⋯O and O-H⋯Br hydrogen bonds inter-actions into a three-dimensional supra-molecular network.
