results of the X-ray diffraction study of the complex [Ni(hfac)2LIm2] synthesized earlier are reported. In the solid state of the complexes [Cu(pfh)2LIm2] and [Co(piv)2LIm2], the paramagnetic ligands are cis-coordinated to the central atom in a monodentate fashion via the donor N atom of the imidazole ring. In the dinuclear complexes [[Cu(pfu)2]2LIm3] and [Cu(hfac)2LTr]2, the paramagnetic ligands are
