【 摘 要 】

This work is the first of a seriesof studies on systems with a common basic structure, Cu-b-diketonate,whose ability to bind to other ligands is regulated by the presence of electron-withdrawinggroups affecting the electronic density on the copper ion. In this paper the[Cu (acac)2] system is studied. Its structure reveals discreteunits linked through H bridges (c.a. 2.7Å). The crystallographicsystem and space group, are monoclinic and P21/n respectively; the cell parametersare a= 10.34Å, b= 4.71Å, c= 11.38Å, beta= 91.78°. Themagnetic behaviour corresponds to a simple paramagnetism with µ= 1.8 [BM];however, a weak antiferromagnetic interaction is observed at lower temperatures.
