Binuclear copper(II) complexes of functionalized 1,2,4-triazoles: Synthesis, structure, and magnetic properties

Copper(II) coordination compounds with 3-(pyridin-2-yl)-5-(2-salicylideniminophenyl)-1H-1,2,4-triazole and 1,3-bis(5-(pyridin-2-yl)-1,2,4-triazole-3-yl)propane have been synthesized. The complexes have been studied by elemental and thermal analysis, IR and electron spectroscopy, electron paramagnetic resonance (EPR), and magnetochemistry. According to X-ray diffraction data, the complexes have binuclear structures in which metal cations are bonded via the nitrogen atoms of two bridging triazole rings.
