摘要：

X-Ray analyses revealed that bis(hexafluoroacetylacetonato)manganese(II) forms with 1-[3- and 4-(N-tert-butyl-N-oxyaminophenyl)]imidazoles cyclic dimer complexes in cls coordination. The long-range magnetic couplings between the two spin 4/2's resulting from the strongly antiferromagnetic short-range interaction between the Mn(II) and the ligated nitroxide radical are regiospecific: antiferromagnetic for 3- and ferromagnetic for 4-nitroxide substitution on the phenyl ring.
