Synthesis and characterization of novel metal complexes of (pentulose-γ-lactone-2,3-enedibenzoate barbituric acid) with some metal ions

New (pentulose-γ-lactone-2,3-enedibenzoate barbituric acid) (L) have been synthesized by reaction of (5-C-dimethyl malonyl-pentulose-γ-lactone-2,3-enedibenzoate) with urea in alkaline media (sodium methoxide). (Ca^+2, Co^+2, Ni^+2, Cu^+2, Zn^+2, Cd^+2 and Hg^+2) complexes of (pentulose-γ-lactone-2,3-enedibenzoate barbituric acid) (L) have been prepared and characterized by (1H and 13CNMR), FTIR, (U.V-Vis) spectroscopy, Atomic absorption spectrophotometer (A.A.S), Molar conductivity measurements and Magnetic moment measurements, and the following general formula has been given for the prepared complexes [MLCl2(H2O)].XH2O, where M = (Ca^+2, Co^+2, Ni^+2, Cu^+2, Zn^+2, Cd^+2, Hg^+2), X = five molecules with (Cd^+2) complex, L = (pentulose-γ- lactone-2,3-enedibenzoate barbituric acid).
