Synthesis and Characterization of Nickel (?) Complexes Derived from Pyrano [2, 3-d] Pyrimidines

In this paper, the syntheses and characterization of bidentate pyrano [2, 3-d] pyrimidine ligands and their Ni () complexes are reported. Magnetic nanoparticles N-propyl-benzoguanamine-SO3H were used as a catalyst for the synthesis of the ligands. The molecular structures of Nickel complexes based on these ligands are described as square planner geometry. The complexes are characterized by FTIR, UV-Vis, molar conductance and mass spectroscopy. The low molar conductance values indicated that the complexes are nonelectrolytes.
