New insights into the thermal stability of Mn12 clusters: The case of complex [Mn12O12(O2CCCH)16(H2O)4]·3H2O and its thermolysis derived [Mn3(O2CCCH)6(H2O)4]·2H2O complex†
Abstract
Two novel Mn12 derivatives [Mn12O12(O2CCCH)16(H2O)4]·3H2O (1) and [Mn12O12(O2CCCC6H5)16(H2O)4]·3H2O (2) have been prepared and characterized. Magnetic measurements confirm that both function as single-molecule magnets (SMM), showing frequency-dependent out-of-phase AC susceptibility signals and magnetization hysteresis curves. Thermal stability studies of both complexes were first conducted in the solid state. While complex 1 undergoes a sudden exothermal
