MAGNETIC AND STRUCTURAL STUDY OF UNSOLVATED [Cu(acac)2], (acac= acetylacetonate)
This work is the first of a series of 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-withdrawing groups affecting the electronic density on the copper ion. In this paper the [Cu (acac)2] system is stu...

| Sumario: | This work is the first of a series of 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-withdrawing groups affecting the electronic density on the copper ion. In this paper the [Cu (acac)2] system is studied. Its structure reveals discrete units linked through H bridges (c.a. 2.7Å). The crystallographic system and space group, are monoclinic and P21/n respectively; the cell parameters are a= 10.34Å, b= 4.71Å, c= 11.38Å, beta= 91.78°. The magnetic behaviour corresponds to a simple paramagnetism with µ= 1.8 [BM]; however, a weak antiferromagnetic interaction is observed at lower temperatures. |
