A new Ni(II)-hydroxy-carboxylate complex was synthesized in aqueous solution. D-(-)quinic acid, a α-hydroxycarboxylate ligand, interacted with Ni(II) at pH 5.5. The crystalline product was isolated and was characterized by elemental analysis, spectroscopic techniques (FT-IR, UV-Vis), magnetic studies and X-ray crystallography. The aqueous speciation work projects a complex picture of the related aqueous synthetic work and relates Ni(II) to biological interactions involved in cellular physiology.
