Poly[tri-μ2-aqua-(μ3-pyridine-2,4-dicarboxylato-κ4N,O2:O2:O2′)barium]

Abstract

In the polymeric title compound, [Ba(C7H3NO4)(H2O)3]n, the BaII ion is ten-coordinated in an NO9 environment by one N atom and three O atoms from three pyridine-2,4-dicarboxylate (pydc) ligands and six water molecules. The μ3-pydc ligands and the bridging water molecules connect the Ba atoms into a layer parallel to (100). The crystal packing is stabilized by O—H...O and C—H...O hydrogen bonds.
