Abstract

In this study, the proton tansfer salt (H2Etppz)(pyzdc)(1) was synthesized from the reaction of 1,4-pyrazine-2,3-dicarboxylic acid (H2pyzdc) with 2-(piperazine-1-yl)ethanol (H2Etppz). The proton transfer salt (1) was characterized using elemental analysis, 1H and 13C NMR, FTIR, UV-Vis techniques. The Mn(II) (2), Co(II) (3), Cu(II) (4) and Zn(II) (5) complexes of proton transfer salt (1) were synthesized. The structures of the complexes; have been suggested according to results of the FTIR, UV-Vis, ICP-OES and magnetic susceptibility methods
