A manganese (II) dimer bearing the reduced derivatives of nitronyl nitroxides
- Abstract:
-
We report the synthesis, magnetic and conducting properties of a new manganese complex [MnII(hfac)2(IMHPhOPh)]2[MnII(hfac)3](IMH2PhOPh) (1), containing the reduced forms (IMHPhOPh and IMH2PhOPh) of the NIT-PhOPh radical (NIT-PhOPh = 2,4‘-benzoxo-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide). Direct current magnetic susceptibility studies revealed the presence of weak antiferromagnetic exchange interactions between the metal ions, within the [MnII(hfac)2(IMHPhOPh)]2 unit. The EPR spectra of 1 exhibit simultaneous contributions of both the monomeric [MnII(hfac)3] and dimeric [MnII(hfac)2(IMHPhOPh)]2 species. Conductivity measurements shown that the electrical conduction of 1 is dominated by Ohm’s law, with a conductance value of 1.3 (6) × 10−9 S/cm.
