Abstract

The reaction of Mn(HCOO)2·2H2O, tBuSaoH2 (3,5-di-tert-butyl-salicylaldoxime) and sodium azide in isopropanol leads to [NaMn3(tBuSao)6] (1). Its structure can be described as a linear trinuclear cluster bridged by oximato ligands. Magnetic investigation revealed that the ferromagnetic coupling interaction is dominant in 1 leading to a ground-state spin ST = 5. 1 shows single-molecule magnet behaviour under zero or 1 kOe dc field with energy barrier Ueff ∼ 10 K.
