A one-dimensional coordination polymer with metal-metal interactions: catena-poly[[triaquabarium(II)]-mu-aqua-kappa2O:O-di-mu-thiosalicylato-kappa4O:O].

ABSTRACT

In the title compound, [Ba(C(7)H(5)O(2)S)(2)(H(2)O)(4)](n), the Ba(II) atom lies on a mirror plane and is nine-coordinated by four bridging carboxylate O atoms of the thiosalicylate ligands, two bridging water molecules and three terminal water molecules. There is an intramolecular S-H.O hydrogen bond between the S and O atoms in the thiosalicylate ligand. A one-dimensional coordination polymer is formed via weak metal-metal interactions along polymeric zigzag chains.
