TI  - Influence of d-Electron Divalent Metal Ions in Complex Formation with L-Tartaric 
      and L-Malic Acids.

AB  - Binary complexes of alpha-hydroxy acids (L-Tartaric acid and L-Malic acid) with 
      d-electron metal ions (copper, cobalt, nickel) were investigated. Potentiometric 
      measurements have been performed in aqueous solution with computer analysis of 
      the data for determination of the stability constants of complexes formed in the 
      studied systems. The coordination mode of the complexes was defined using 
      spectroscopic methods: electron paramagnetic resonance (EPR), ultraviolet-visible 
      (UV-Vis), circular dichroism (CD), and infrared (IR). Results of the equilibrium 
      studies have provided evidence for the formation of dimers with copper(II) ions 
      and monomers with cobalt(II) and nickel(II) ions.
