M. Soler et al., A third isolated oxidation state for the family of [Mn12O12(O2CR)(16)(H2O)(4)] compounds. Synthesis, characterization and single-molecule magnetism properties of (PPh4)(2)[Mn12O12(O2CR)(16)(H2O)(x)] (x=3 or 4), POLYHEDRON, 20(11-14), 2001, pp. 1279-1283
The synthesis and characterization are reported of the two-electron reduced
version of the [Mn12O12(O2CR)(16)(H2O)(4)] family of single-molecule magne
ts (SMMs). Reduction of the neutral complexes with 2 equiv. of PPh4I gives
the (PPh4)(2)[Mn12O12(O2CR)(16)(H2O)(x)] (x = 3 or 4). The crystal structur
e shows the overall Mn-12 structure is maintained, with a 2Mn(II), 6Mn(III)
, 4Mn(IV) trapped oxidation state description. Magnetic characterization in
dicates a S = 10 ground state and retention of SMM behavior. (C) 2001 Elsev
