Synthesis and electron spin resonance studies of a Co(II) complex with a tetradentate macrocyclic Schiff base ligand

Abstract: A M I K I~I REI VFUI. V I \ C F N~O M A L~T F S T A .and BRLJCF R MCGARVEY Can J Chem 55.70 ( 1977) The synthesis, physical properties, and electron spin resonance of frozen solutions of COTAAB(NO,)~ (TAAB = tetrabenzo [b,f,j,n] [1,5,9,13]tetraazacyclohexadecine) are reported.The spin Han~iltonian parameters were elucidated by simulation of spectra assuming axial g and j9Co hyperfine tensors and including nuclear quadrupole and Zeeman contributions. Electron spin resonance spectra in solvents such as methan… Show more

“…Therefore the experimentally determined magnetic susceptibility for a cobalt complex will only correspond closely to the calculated spin-only value when the sample is cooled to liquid helium temperature. At other temperatures, the second-order Zeeman mixing terms make an important contribution to the magnetic susceptibility (18). Wicholas and Drago (19) have assumed that the mechanism for the electron spin transfer and distribution in a Co(I1) complex is similar to that in the corresponding Ni(I1) complex.…”
