摘要：

The dinuclear (mu(2)-acetate)bis(mu(2)-phenoxide)di-copper(II) complex, 1 with a tetradentate ligand, L (L=2,4-di-tert-butyl-64{[(2-dimethylaminoethyl)-(2-hydroxybenzyl)-aminol-methyl}-phenol) has been synthesized and characterized. The single crystal X-ray structure of the dinuclear complex was determined. Variable temperature magnetic susceptibility measurement showed that the two copper(II) centres are strongly anti-ferromagnetically coupled. The structural study revealed that the Cu-Cu distance (2.911 angstrom) is very close to the distance observed in dinuclear copper(II) acetate. The average Cu-O-Cu angles (similar to 87 degrees) are found to be the lowest amongst the examples reported so far. (C) 2010 Elsevier Ltd. All rights reserved.
