Abstract

The paper describes the crystal structures and magnetic properties of complexes of copper(II) hexafluoroacetate (Cu(hfac)2) with stable pyrazole-substituted iminonitroxyl radicals containing the pyrazole substitutuent in the second position of the 2-imidazoline cycle (L). A new group of [Cu(hfac)2]3(L)2 complexes is found, in which L performs a bidentate-bridge function due to the coordination of the imine N atoms of the pyrazole and imidazoline cycles. It is shown that in the solid complexes there are Cu2+-N=C-N-•O exchange routes with high-energy ferromagnetic interactions (∼60-100 cm-1).
