Notes:
Temperature-dependent paramagnetic susceptibility data for two cyclic dimer complexes of bis(hexafluoroacetylacetonato)manganese(II) with 5-tert-butyl-1,3-phenylenebis(N-tert-butylaminoxyl) and 4-(N-tert-butyl-N-oxyamino)pyridine have been analyzed to obtain two sets of two intramolecular exchange coupling parameters J1 and J2. A previous model, based on one of these interactions being much weaker than the other, could not be explicitly correlated to these actual exchange-coupling parameters. However, the energy levels of the low-lying spin states were found to be reproduced reasonably well by the approximate method.
