Abstract

The reaction of [Mn₃O(O₂CR)₆(py)₃](ClO₄) (R = Me, Et) with methyl 2-pyridyl ketone oxime (mpkoH) in a 1:3 molar ratio in MeOH/MeCN leads to [Mn₃O(O₂CR)₃(mpko)₃](ClO₄) in 80-90% isolated yield. Ferromagnetic exchange interactions between the three Mn_III ions in the nonplanar [Mn_III3O]⁷⁺ triangular core lead to a spin ground state of S = 6; single-crystal studies reveal the temperature and sweep rate dependent hysteresis loops expected for a single-molecule magnet.
