Crystal structure and magnetic properties of the binuclear copper(II) complex with 2,6-diformyl-4-tert-butylphenol bis(imidazolinylhydrazone)

This is the authors' abstract. We don't add key points for this paper.

The binuclear copper(II) complex with 2,6-diformyl-4- tert -butylphenol bis(imidazolinylhydrazone) (H 3 L), [Cu 2 (H 2 L)Br 2 ]ClO 4 ( I ), was synthesized. The structure of complex I was determined by X-ray diffraction analysis. The antiferromagnetic exchange interaction (2 J = −108 cm −1 ) translated through the phenoxide oxygen atom is observed between the copper(II) ions. The exchange parameter was calculated by the quantum-chemical “broken symmetry” method.
