Synthesis, extractive properties towards transition metal ions and X-ray crystal structure of its nickel complex %V 32 %X A new tetradentate N2O2-type Schiff base, bis(2-hydroxypropiophenone)-1,2-propanediimine (L), was synthesized by the reaction of 1,2-propanediamine with 2-hydroxypropiophenone in EtOH. The Schiff base is able to extract Co-II, Ni-II, Cu-II and Zn-II ions in aqueous NaNO3 media into a CH2Cl2 organic phase via a cation exchange mechanism. The observed extraction order was as follows: Cu-II > Ni-II > Co-II > Zn-II. Reaction of nickel acetate with the Schiff base in EtOH afforded the neutral complex Ni center dot L. Single crystals of this complex were obtained from mixed CHCl3-EtOH (3:1) solvent and its structure was determined by X-ray diffraction. Crystal data for Ni center dot L center dot CHCl3: triclinic, space group P1, with a = 9.005(2) angstrom, b = 9.625(2) angstrom, c = 14.212(4) angstrom, V = 1136.8( 5) angstrom(3), alpha = 106.06(2)degrees, beta = 106.06(2), gamma = 105.10(2)degrees, and Z = 2. A near square planar structure is observed for the studied complex.
