Synthesis, crystal structure and battery-like studies on a new acylpyrazolone-based mixed-ligand Cu(II) complex
A new mixed-ligand Cu(II) complex, [Cu(pyr)(bpy)(OH 2 )]ClO 4 (1), was synthesized from 4-acetyl-3-methyl-1-phenyl-2-pyrazoline-5-one (H-pyr) and 2,2-bipyridine (bpy). Single-crystal X-ray diffraction, elemental analysis, and FTIR and UV–Vis spectroscopy were used to confirm its structure. The pyr l...

Single-crystal X-ray diffraction, elemental analysis, and FTIR and UV–Vis spectroscopy were used to confirm its structure. The pyr ligand is the monoanionic deprotonated form of the H-pyr enol tautomer. Additionally, the complex’s battery-like capabilities were investigated. The newly synthesized complex possessed a high specific capacity and provided sufficient energy density for SC devices.
