Description: The hydrothermal reaction of SrCO3 and 2-bromobenzoic acid in CH3OH–H2O afforded the SrII title polymeric complex, [Sr(C7H4BrO2)2(H2O)2]n. Within the coordination sphere, the SrII ion is located on a crystallographic twofold axis, and is coordinated by eight O atoms from two water molecules and four carboxylate groups of 2-bromobenzoate ligands in an irregular coordination geometry. Two μ3-carboxylate groups of the 2-bromobenzoate anions bridge two symmetry-related SrII 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 interactions into a three-dimensional supramolecular network.
