| 摘要: | A novel double helical dicopper(II) complex was synthesized by reaction of a polydentate ligand L = 2,2′-bipyridyl-6,6′-bis(2-acetylpyrazinohydrazone) with copper(II) perchlorate in CH3CN. The self-assembling process was studied by UV-Vis spectrometric titration experiments which revealed the formation of dinuclear complexes [Cu2L2](ClO4)4. The structure of dicopper double-helicate was confirmed by X-ray diffractometry. Each copper(II) center occupies a distorted octahedral environment. Variable-temperature magnetic measurements reveal weak antiferromagnetic interactions between Cu(II) ion centers with J = −0.63 cm−1. |
