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...

In this paper the [Cu (acac)2] system is studied. Its structure reveals discrete units linked through H bridges (c.a. 2.7Å).
