catena-Poly[[triaquanickel(II)]--5-hydroxyisophthalato]

X.-H. Sun

Abstract: The title compound, [Ni(C₈H₁₀O₈)(H₂O)₃]_n, a one-dimensional chain complex of 5-hydroxyisophthalate with Ni²⁺, was prepared by a hydrothermal reaction. The coordination geometry around the Ni atom is distorted octahedral with the central Ni atom bound to three O atoms of two 5-hydroxyisophthalate ligands, which act as bidentate and monodentate ligands, positioned in the equatorial plane. The three remaining coordination sites are occupied by water molecules. In the crystal structure, an extensive hydrogen-bonding network is formed, which involves the coordinated water molecules and the ligand substituents.
