Abstract
A series of bis(4,4,4-trifluoro-1-R-1,3-butanedinato) Co(II) complexes with imino nitroxide radical(IM2py), [Co(Rtfc)2(IM2py)] (R = trifluoromethyl, phenyl, naphthyl, thienyl), was prepared and characterized by the X-ray analysis which demonstrated the stereospecific formation of the trans(CF3)-isomer with the trans disposition of the CF3 groups. The significant substituents effect on the UV-Vis spectra and magnetic properties were discussed in consideration of the inversion of the dπ(t2g) orbital levels leading to the orbital orthogonality or overlap with the SOMOπ* of IM2py in terms of the AOM parametrizations or spin-paring energy.
