Crystal, molecular structure, and magnetic properties of bis-[4-(2'-oxo-3',3',3'-trifluopropylidenyl)-2,2,5,5-tetramethyl-3-imidazolin-1-oxyl] copper(II) Cu(C10H13F3N2O2)2

The crystal structure of the complex of copper(II) with the paramagnetic ketone 4-(2'-oxo-3',3',3'-trifluorpropylidenyl)-2,2,5,5-tetramethyl-3-imidazolin-1-oxyl has been determined and the statistical magnetic susceptibility of the polycrystalline material was measured by the Faraday method over a temperature range of 4.2-3000K. A theoretical interpretation of the magnetic properties of the coordination compound was carried out using an isotropic exchange model. The results of the calculations agree with the experiment
