SYNTHESIS AND CHARACTERIZATION OF PROTON TRANSFER SALT OF PYRIDINE-2,6-DICARBOXYLIC ACID AND ITS Ni(II) AND Cu(II) COMPLEXES

Abstract

In this study the proton transfer salt (H₂Meppz)(Hdipic)₂ (1) was obtained by the reaction of N-methylpiperazine (Meppz) with pyridine-2,6-dicarboxylic acid (H₂dipic). The metal complexes [Ni(H₂O)₆][Ni(dipic)₂].(Meppz).5H₂O (2) and (H₂Meppz)[Cu(dipic)₂].2H₂O (3) were synthesized by the reaction of proton transfer salt (1) with Ni(CH₃COO)₂.4H₂O and Cu(CH₃COO)₂.2H₂O. The structure of proton transfer salt (1)  was characterized by ¹H and ¹³C NMR, FT-IR and UV-Vis spectra and elemental analysis techniques. The structures of the complexes have been suggested according to data obtained from FT-IR, UV-Vis, ICP-OES, magnetic susceptibility and elemental analysis methods.
