Synthesis, Characterization And Spectral Behavior of Some Mixed-Ligand Copper (II) Complexes Involving 3,4-Pyridinedicarboxylic Acid and Diimines

Abstract

Six mixed-ligand complexes of copper(II) [Cu 3 (pdc) 2 (bipy)].2BF 4 (1),[Cu 4 (pdc) 2 (4,4ꞌ-Me 2 bipy) 2 (dmf) 2 ].4BF 4 (2), [Cu 4 (pdc) 2 (5,5ꞌMe 2 bipy) 2 (dmf) 2 ] .4BF 4 (3), [Cu 4 (pdc) 2 (phen) (dmf) 2 ].4BF 4 (4), [Cu 3 (pdc) 2 (dmp) 2 (dmf) 2 ].2BF 4 (5) and [Cu 3 (pdc) (bathophen) (dmf) 4 ] .4BF 4 (6) have been synthesized by solvothermal method in 3:1:1 metal-to-ligand molar ratio. The synthesized complexes have been characterized by elemental analyses (C, H, N), IR-spectra and electron paramagnetic resonance (EPR) spectra.
